Mothership Zeta bugs

All platforms

 * Paladin Hoss (with a Flamer and 10mm pistol), Initiate Pek (unarmed) and/or Brotherhood of Steel Paladin may appear out of nowhere in Mothership Zeta. This is part of the Lost Initiate quest bug. Loading an older save doesn't seem to fix this.
 * If you save the Crypto Lab's generator for last, you will not be able to use the teleporter. This will get you locked in the lab where you must freeze the aliens and Elliot's team, with no way back to Sally!
 * Killing Elliot may fix the problem, but he must be with you when you kill him. Save before trying.


 * If a container is opened on its side with one's back to an unmovable object, the player will be pushed into the object or wall and become stuck even when the container is closed, only noclip (tcl) (PC only) or reloading a save (Xbox 360) will fix this.


 * If you ask Sally "Are there any cool secrets on the ship" (her Child at Heart option) then interrupt her as she climbs into the vent (near the closed door she opens to show you her stash) she will reset and run back to the engine core, leaving the room locked permanently.


 * The World Map in the Pip-Boy incorrectly displays that you are in Megaton on the Capital Wasteland map, it can also display random areas such as Shalebridge or Tennpenny Tower. (This could be explained because you are in a ship orbiting the earth)


 * When you kill a Guardian Drone, while searching in the bottom left hand corner (where the weapons image usually is) the drone cannon has a square with a line through it and says PipOS Error -26 [File Not Found]. The cannon in the looting screen is at full health but when taken the health is less.


 * When you get General Chase's Overcoat in the garbage disposal area, it will appear as a suit of Winterized Combat Armor, or the armor will become the texture of any random thing around you.(Xbox 360 and PS3)


 * In the Cryo Labs when you get to the point where you have to freeze the Aliens to continue, in the room there will be three Wastelanders (or Elliot Tercorien's squad if he came with you.) The dead, frozen bodies will be on the tables, with a leg or arm sticking up in the air. Although that is supposed to happen because they're frozen, if you use the "grab" command on any of the corpses, the limbs will become limp, and they will fall as if they were a regular corpse.


 * There have been times when looking down at the Earth just after the Space walk, Earth's image will just become black.


 * When using the drone cannon in VATS, the shots are fired straight even though the projectiles have weight, making them fall to the ground usually before coming near the target.


 * There is also a glitch if you have the Mister Sandman perk that grants you infinite exp when doing it on Sally.

PC

 * When the PC gets abducted and the first cut scene is finishing, the aliens may freeze and the PC may get stuck, unable to move or progress and the game hangs up, making the player unable to complete the add-on.
 * There may be a way to fix this. If you happen to be running a mod called "Purge Cell Buffers", then that may be what was causing this bug. Try disabling PCB for the duration of Mothership Zeta and you should be able to get past this cutscene.
 * If you are running FOOK2, disabling 'FOOK2 - Mothership Zeta.esp' may allow you to pass the cut scene. It can be re-enabled after arriving upon the alien ship.
 * If still stuck try bringing up the console using the "`" key and typing "enableplayercontrols"
 * After using the "enableplayercontrols", you might still find Somah nowhere to be seen. If this happens, you can input the following commands: "prid xx000988" (with xx being the load order of the Zeta.esm file in the mod manager), "disable", "enable". Somah should materialize in front of you, allowing you to continue the quest.
 * Still in the holding cells, when you have to free Sally, she might be missing. Unlike Somah, the "disable"/"enable" commands don't seem to work. However you can input in the console: "prid xx000987" (with xx being the load order of the Zeta.esm file in the mod manager), and then: "moveto player". She will appear before the player, then proceed to open the door. (tested only after disabling the force fields in the cells).
 * Once reaching the Cryo-chambers Paulson may be missing from his tube. If so he can be safely added in by bringing up the console and typing. "prid xx003304 (with xx being the load order of the Zeta.esm file in the mod manager), "disable", "enable". Paulson will appear in his tube, allowing you to continue with the quest normally.


 * Two invisible turrets (perhaps more) in the Living Quarters section. Though they do not attack, when you come within range your 'Hidden' status will change to 'Detected'. They can be destroyed through conventional fire or explosives if one pinpoints their location.


 * When receiving the objective to disable the Death Ray, if you go into the armory and grab the Destabilizer and test it on the Brahmin you strangely complete the quest and it tells you to go to the bridge. Sometimes not even this is required, and the quest will just randomly be marked as complete.


 * During the "This Galaxy Isn't Big Enough..." quest, after activating the Engine Core teleporter to bring Sally and any of the other surviving NPC's up, and after being given the objective to "Disable The Death Ray" and/or "Make Your Way To The Bridge", these objectives may auto complete -- moving you to the objective "Defeat the Alien Captain" without any interaction by the player. There does not appear to be a specific trigger for this happening and it may happen at any time without any notification given to the player that these objectives have been completed. This results in being unable to complete "Disable the Death Ray" quest and prevents you from entering the Living Quarters area. Saving the game with the problematic objectives still incomplete on a frequent basis, and reloading your game if they auto complete without the players interaction does work, but is very tedious. Once these two objectives have been properly completed by the player, there does not appear to be any ill effects to any of the other objectives in this quest. Hopefully this problem will be addressed in a future patch.


 * When you go the the Bridge to defeat the Alien Captain in the final mission, after Sally comes through the teleporter and opens the first door, all NPC's (including Sally) may immediately return back through the teleporter and all stand at the door downstairs which is inaccessible, which means you cannot continue any further through the mission as you need Sally to open all the doors. To fix this, try talking to all of the NPCs while Sally is away opening the first door. Then when the door is open, push Sally to the end of the doorway and she'll make her way to the second door instead of turning around and running away.
 * Sometimes all the company may become stuck or run into the wall at the right of the second door if Sally opened the first one.
 * In some cases, Sally won't open even the first door when you turn the teleporter on. All NPC's, including her will immediately teleport back to the engine core and run to inaccessible door.
 * If the above options don't work, 'tcl' cheat to get through the door and finish the DLC.


 * It is possible to restore access to the INACCESSIBLE doors after the add-on is completed, using console commands. Go up to one of the disabled doors, hit the tilde key to enter the console window, and click on the door to see its formID. Then type in "prid 0X00d85f", where X is the formID (for example, if the door's formID is 0100d85f, type 'prid 0100d85f"), then hit enter. Type "disable" again, hit enter then exit the console window. All doors should now be restored. Doing this will make the door leading to the bridge teleporter inaccessable, so after you're done exploring simply walk into the Engineering Core and repeat the process you used to open the doors, execpt after entering the prid type enable into the console. This will lock the doors again but reopen the door to the bridge teleporter.


 * The game may randomly crash whenever you equip the Drone Cannon.


 * If you have RL-3 as a companion, when you leave the Mothership he will be near the crash site. If you go into the building at Greener Pastures disposal site nearby, he will clone himself. If you tell him to wait, one of the two will become hostile and attack the other.


 * After the main quest, some respawning aliens that you do not kill can become allied with you.


 * After the quest 'Among the Stars' Sally will open the first door, but for the second door she will go on the opposite side of the door where vent is absent and just stand there after a while assuming the door is opened.


 * After completing the DLC's quest line and then leaving the mother ship will sometimes cause texture issues when your character is in first person view which turns the pip boy and pip boy glove into a bright orange/pink colour, reloading the save in which the glitch occurred and then reloading your most resent save seems to fix the problem.
 * Completing the space walk resets your running speed to default instead of the value you had before it. Breaks one or the other speed plugin. Use "player.setav speedmult xxx" to fix, where xxx = your desired speed. This also gets saved, no need to re-enter it.

Xbox 360

 * Sometimes, none of the teleporters will work. (Resetting Xbox will fix this)
 * Sometimes when you start Mothership Zeta all the aliens after the first part where you have to escape with Somah are wearing shields although you can still kill them normally. It makes it difficult to pick out the regular shielded aliens. (Needs confirmation)
 * If you target enemies as they are waking up from cryo-sleep (standing inside the cryo-pod but targetable) in V.A.T.S you may become trapped in V.A.T.S and have to reload your save.
 * After defeating the first aliens in the cell at the beginning, Somah will keep fighting the player to the death.
 * After completing Mothership Zeta the character/lone wanderer may be bathed in a red or orange light. This may be a result of a teleporter lighting effect continuing after you have teleported. Restarting the Xbox seems to fix the problem. Another solution is to set yourself on fire with a Heavy Incinerator to reset the glow effect. Unequipping your armor may also fix the problem. (Confirmed)
 * After destroying Cryo Labs generator, it becomes impossible to leave the area through either the transporter or the doors (status of "Requires Key")- Sign out of Xbox live and restart your load the teleporter will work.
 * When destroying the generators, if the player enters the Engine Room, and kills all the enemies there, before destroying the last generator, the game will not register the deaths of the aliens, and red cursors will appear, and footsteps can be heard, the player will also be attacked even though the alien corpses are clearly visible. The only way to fix this is by going around and shooting all the corpses of the already dead aliens.
 * If you attack Toshiro Kago and he becomes hostile, Elliot may run away and disappear from the game.
 * If you have not yet completed Who Dares Wins, upon entering Mothership Zeta, the game may alert you that you've discovered the presidential metro location. The "Who Dares, Wins" quest now has "enter the presidential metro" marked as completed.
 * After you finish your space walk, Elliot's forehead is see-through. (Confirmed) It may be he was supposed to have foil wrapped around his head (you can ask him "what's that you've got there?" and he'll call it a "teleport blocker" despite the fact that there's nothing actually there). This may be a reference to the mind control blockers the kids wore in the movie Signs. Elliot apparently watches a lot of movies, as he seems to draw from these to explain why the aliens want us. Somah also presents the same bug.
 * When you fight through the Waste Disposal area and get to the end, the teleporter matrix may not work. This stops you from completing the DLC unless you reload a save before you enter the area, and then don't enter it.
 * Toshiro Kago may simply pick up a combat knife somewhere to use instead of his Samurai sword (which means you can't shoot his Katana out of his hand to get it without killing him).
 * In the Cargo Hold, when going to unlock Reid Underwood's safe with the terminal it fail to unlock the safe and thus making it impossible to obtain his stash. There is no way to fix this. (Needs Confirmation)
 * When in the Experimental Weapons area, after you head to the far end where Radscorpions and Raiders spawn in a room below for you to test your weapons on, Albino Radscorpions will spawn constantly (around 20 were noted) and will stand around trying to find a way to attack you. The Xenotech Expert perk may also be awarded even if you didn't attack any of the targets. (Confirmed.)
 * Sometimes when the player picks up the Drone Cannon Ex-B (correctly labeled on the floor) it will turn into a regular Drone Cannon.
 * After you blow up the controls on the wall in the Robot Assembly room, you can actually walk through the glass right beside the wall and be in the assembly line. Nothing except the glass around it is solid.
 * If you die or change the difficulty immediately after using the first healing arch there is a possibility that further healing arches will not be usable, either to heal or modify (although the options do appear, choosing to activate an arch does nothing).
 * When entering the Garbage Disposal area, teleporters may lock. You have no choice but to load up a previous save and avoid that area. This may also happen in the Living Quarters.
 * Exiting the game and restarting can fix this bug
 * If the player completed "This Galaxy Ain't Big Enough..." quest and heads back to the Capital Wasteland and goes back on Mothership Zeta, Paulson will still be there, but the NPCs' will tell you that he left the ship.
 * Save games may become unloadable (crashing on the loading slides) after saving on the mothership. Pre-abduction saves appear to be unaffected. (Confirmed)
 * (Fix does not work all the time) Restart the Main Quest in Mothership Zeta, save, then load the original unloadable file
 * Sometimes while fighting an Alien, it will just disappear and may reappear right behind you or somewhere else nearby.
 * Sometimes after completing the spacewalk, and trying to activate the lift for your allies to join, they may never appear, and makes it impossible to have the door unlocked to continue. This may be fixed by uninstalling and then reinstalling the patch. (Confirmed)
 * Another way to solve this problem is to simply turn off your Xbox and then turn it back on.
 * While in the Cryo-Chamber with Elliot's fallen unit, if you run in to the back room and unfreeze the two living members before Elliot enters the room and begins dialogue the doors can lock permanently preventing any kind of exit.
 * While in the Experimentation Lab, when you destroy the generator in order to bring down the force-field blocking the exit, the animation for the force-field will disappear but the door will still be blocked. Firing a weapon at the doorway causes a ricochet (energy impact in the case of energy weapons), just as if the force field were up. Loading a previous save does not seem to fix this. (Confirmed)
 * Saving and loading the save again should fix this.
 * If you have the Gauss Rifle you may use it to knock down any of your NPC allies in the Bridge (assuming they are alive) and when they are knocked down you keep pressing "A" and you can reverse pickpocket and subsequently pickpocket all their unique items. (Confirmed)
 * Not necessarily a bug. Any knocked down character can be looted and reverse pickpocketed although you may have to wait for them to be knocked down again after planting the items on them.
 * After completing the Among the Stars quest, and you meet up with Sally and Somah, the hologram of the alien will not appear, therefore the door will not unlock and all you can do is stand there and stare at the Earth through the window in the ship, It seems if Elliot stays alive this problem will not occur.
 * If you had the Winterized T-51b Power Armor in your inventory before you got on the ship and the aliens took it, when you get it back and if started but never completed the quest, You Gotta Shoot Em' In The Head, you will complete it upon receiving your armor back and you will get the achievement.
 * When in the Cryo Lab if you freeze yourself and save your game, while your character is still frozen, and then load that save your character will remain lying down on the ground and won't get back up making that save unusable. Using a previous save is you're only option.
 * In the Cryo Lab if you teleport out before the generator explodes, it wont register on the game as achieved, You must stay in the room for the explosion. Also the teleporter back to the room will not function, you must reload a save to get it to work.
 * In the Cryo Lab, if you freeze Elliot, you will be able to pickpocket him when he is on the floor without negative karma.
 * When shooting any chair, blood will come out. (Confirmed)
 * After finishing the add-on and entering the Engineering Core, the game may constantly crash while loading back to the Bridge. (Confirmed)
 * After the spacewalk, Somah may not teleport to the Observation Deck with the others. If you teleport back to the Engineering Core, she will still talk about the Death Ray and give you the quest to destroy it. Then if you teleport back, she follows.
 * After finishing Mothership Zeta, the player may not be able to return to the ship once he/she sets foot on the wasteland, due to crashes during the loading screen. (Confirmed)
 * The console will freeze when you go through the portal to the Bridge from the Engineering Core. (cache issue)
 * The console will freeze when going to the Bridge from the Capital Wasteland while overencumbered. (cache issue)
 * After destroying the attacking alien ship the Earth may be missing sections. (Confirmed)
 * a large black diamond of sorts takes the place of certain parts of the ship. A version of this "glitch" occurs on the PC. If you no-clip and look and the earth at different angles in front or under the Bridge, graphical pieces appear and disappear, even if the earth cannot be seen through the front window of the Bridge. It may be that the earth is not supposed to be seen at all and the glitch is actually seeing earth. This would make sense considering access to the weapon on the bridge. The story may be that the ship was re-positioned, in reality this means that the graphical representation of earth may have been disabled only at viewing angle from the Bridge. The glitch may be seeing through or past an unloaded black texture.
 * After falling from the elevator in the maintenance level, jumping up the scrap pile to the character's rear may result in being trapped and requiring a reload.
 * After completing the spacewalk if you happen to have Chinese Stealth Armor in your inventory its condition will be broken (Confirmed)
 * (may not be a bug) After a certain point in Mothership Zeta, you will not be able to use the health generators.
 * happened sometime after the weapons lab
 * After using the teleporter to access the ships bridge, upon walking forward your character falls through the ship. After reloading the save you are unable to walk forward and your shots will stay in mid-air. If the rounds are explosive, they will NOT explode.
 * The Holotape that accompanies General Chase's Overcoat may fail to play i.e choosing to "Play Audio" fails to produce any sound and may cause the game to crash soon after. (Confirmed, without crash)
 * Trying to acquire the 2nd Drone Cannon Ex-B may cause the game to crash when trying to pick it up.
 * Each time Somah and Elliott Tercorien needed to use a teleporter (to escape the Cryo Storage area for Tercorien and to get down from the 2nd floor to the first floor in the Robot assembly section for Somah), they would froze on or near the teleporter and would not follow. The dialogue box would not open up to ask them to continue to follow. In each case it was necessary to return to a prior save and start over. Eventually the bug did not occur and the NPCs would assist as intended.
 * While working on destroying the Mothership Zeta power generators in the 3 sections needed for the quest "Among the Stars", the Paulson character died while in the hangar, so bug is untested on him.
 * After getting to the observation deck with Sally, Paulson, Elliot and Somah ALL of the characters just stand there and do nothing, halting the progress through the Mothership.
 * Maintenance level teleporter is lit up but doesn't work. Solution: Re-start your Xbox 360 and load up the game and Maintenance level teleporter should work again.
 * After getting the "Xenotech Expert" perk and moving on to the experimentation lab, your character will simply disappear in 3rd person mode.
 * this can be fixed by restarting the Xbox.
 * After completing Mothership Zeta, if you try to enter Tenpenny Tower, the game will freeze.
 * Upon returning to Mothership Zeta, the teleporters to and from the engineering core as well as the teleporter back to earth may malfunction and no longer work, stranding you in space.
 * it is always recommended to save prior to returning to Mothership Zeta.
 * At the end of the spacewalk, when you are transported up by the beam, you can see your arms and hands, but your hands are wearing fingerless gloves. Later, you are wearing the spacesuit gloves.(Break in Continuity).
 * After you obtain your Pip-Boy, your hand will always have a fingerless glove, regardless of armor/clothing type. So it's more of a known limitation, rather than a bug.
 * If you have a follower before beginning Mothership Zeta, tell them to wait at your house (Megaton or Tenpenny Tower). Then, when you complete This Galaxy Ain't Big Enough... and upon return to the Wasteland, your follower will come running at you and begin following. Because of this, the game thinks you have no follower and it will be possible to hire another follower.
 * After completing Mothership Zeta, if you have not already triggered the events at Andale, when you arrive there, the residents will all be standing around the shed, and upon approaching them they will confront you about why you were poking around in the shed, regardless of the fact that you had just arrived.
 * After completing the spacewalk, the teleporter to enginering room activates but is unusable. This leaves you trapped and unable to continue. (Confirmed)
 * Upon entering the Weapons Lab, it is possible that weapons will not fire correctly, and will not fire any sort of projectiles when triggered. They might fire on their own when exiting the pause menu or PIP BOY, or when loading a save game. The Drone Cannon might fire like a machine gun, making survival even more difficult. Loading a previous save carried the bug to that point in the game. Using VATS may cause a lengthy slo-mo animation of the player character in attack stance doing nothing whatsoever, while the enemy attacks. The only way to fix the bug is restarting the game. (occurred on Xbox 360 and PC) (Needs confirmation of it happening on the PS3 before being moved to the "All Platforms" section)
 * At the teleporter leading from Biological Research to the Death Ray Hub, when all of your teammates are standing idly by, waiting for you to enter ahead of them, if you attack Elliott with sufficient damage to the legs (possibly so that his now "fleeing" status would realize that it cannot outrun you, and thus choose the next best option) he will escape from you into the teleporter which leads to the Death Ray Hub. However, once you pass through the device, he does not appear on the other side, as per the flow of the story. [ Edit: I wonder what would happen if you let Elliott disappear into this teleporter to nowhere, and then completed the rest of the storyline. Would he be waiting for you at the end, or would he disappear for good? ]
 * After completing Mothership Zeta, some of the respawning aliens may randomly be allied with you. (In this authors case, it was a trio of aliens standing in a corner in the Steamworks)
 * It is possible that after downloading Mothership Zeta that the previous installation such as the Pitt and Opperation Anchorage will become inactive with weapons and armor from them missing. Not fixed by restarting game or by loading previous save. (Confirmed, Unfixable) (Might be fixable by deleting all the FO3 DLC and reinstalling them after clearing the cache and re-patching)
 * It is possible that after the instalation of Mothership Zeta that your play will no longer have the ability to gain exp and that previos saves will become corrupt with the same glitch. This is fixed apon restarting game. (needs further confirmation)
 * After completing Mothership Zeta, the game will freeze/crash when attempting to enter the museum of history and subsequently Underworld. No way to fix this but can restore and old save after restarting xbox (confirm?)
 * Upon the entrance to the Observation Deck, an error message may come up, telling the player that a nonexistent door cannot be opened until the chamber is depressurized. After hitting the "OK" button at the bottom of the message, the message will continue to pop up until a certain point in the Observation Deck is reached (this point is very nearby and reached simply by walking forward). Once the player reaches this area, the message will stop appearing.
 * Once you complete the spacewalk and enter the room after the decompression room, the transporter you are supposed to activate to allow Sally and the rest of the people to gain access to your level of the ship is already active but your party doesn't come to you. Thus you are stuck in that room and can't move since you require Sally to open the door to progress.

PS3

 * When first beamed up to the mothership, the game may freeze at the probe scene. The game won't progress, but you can pause, and an alien in the background is moving. (confirmed)
 * This can be fixed by deleting the game data cache and/or reloading a save from the wasteland, and re-entering Mothership Zeta. (confirmed)
 * However when an older save is loaded your arms glow the colour of the abduction ray when in third person. Can only be fixed by restarting the console. (confirmed)
 * When older save is loaded you start off looking between the players legs. This is fixed simply by moving.


 * When returning to the wasteland, your followers may be at the beacon waiting for you even if they were asked to wait at your house. As there are often sentry bots and Albino Radscorpions around, make sure they are well armed and armored before you leave for MZ.

While on the observation deck en route to the bridge: Sally will just stand on the glass floor which overlooks the Earth, and not open the door. This makes it impossible to advance any further. Some users have reported fixing this issue by loading an earlier save. May take several times. Leaving and re-entering the area may also work.
 * During the "This Galaxy isn't Big Enough" mission,


 * During the "The Quest for the Stars", Somah may go up to the top level and stay there. This causes the game not to continue later on during "This Galaxy ain't Big Enough". Reloading an earlier save seems to fix this, as Somah will come through the teleporter in "This Galaxy ain't Big Enough" anyway.
 * After finishing Mothership Zeta, the player may not be able to return to the ship once he/she sets foot on the wasteland, due to crashes during the loading screen.
 * During the Quest This Galaxy Ain't Big Enough... When you turn on the Teleportation Pad Nobody will come. (Confirmed on PC too).
 * Deleting the game data (Not the save data) fixes this.
 * After stageing the fight with Somah and killing the Aliens, she may remain hostile to you.


 * After finishing Mothership Zeta the teleporters to Engineering Core and back to The Capital Wasteland will no longer work, stranding the player on the ship forever!
