Broken Steel bugs

Unable to complete quest

 * If you have not completed The American Dream, you may freeze within 5 feet of Elder Lyons and be unable to talk or move. The quest does not continue, and Elder Lyons does not speak. Weapons cannot be drawn upon entrance to laboratory.
 * Reported incidents of an "invisible barrier" appearing any certain points i.e. the utility door up the earth mount and the door to Tesla coil leaving players trapped if they jumped in, this bug is on the Xbox 360 version, only one barrier appears to have dodgy coding and blocks important in-game places.
 * After speaking to Elder Lyons about the events of the past two weeks, he directs you to Scribe Rothchild. After asking Rothchild for an update on the situation, he tells you to follow him to the map, but he fails to lead you there, instead carrying on with his daily routine.
 * A way to fix this is talking to Rothchild repeatedly (pushing E nonstop), and pushing him towards the map (i.e walking into him), then enter console and type enableplayercontrols and follow him 'till he finishes talking. Enter conversation and hey presto the game goes on! (Note this only works if you're both in the Citadel Labratory).


 * Similar to the above bug, once Broken Steel is completed with the 'good' ending and your Vertibird lands back in the Citadel courtyard for Lyons' speech, the speech never occurs. Your character is locked into the 'listening' pose but Lyons, Rothchild, and Sarah simply walk off and continue their daily routine leaving you stuck there. This makes the good ending impossible to finish, effectively defaulting you to blowing up the Citadel, as doing so does not involve a speech at the end.
 * Fix for this issue: After the game loads the Citadel and you are stuck at this screen, open the console via the tilde "~" key and type "enableplayercontrols". This should give you control over your character, and then you can run to Elder Lyons and talk to him, thus completing the quest.


 * Paladin Tristan does not appear at quest marker for "death from above"
 * fix - type in the console prid xx005689 (enter) next type enable (enter) he should appear walking at you from the broken truck.


 * Despite having finished the main quest for the add-on, when returning to Jefferson Memorial the water is not flowing from the pipes. Also, Liberty Prime is still there killing randomly spawning Enclave soldiers and Sentry Bots. Also Jefferson Memorial no longer has a map marker, the only way to get there is via foot.
 * After the, "Two Weeks Later" cutscene, you are given full control of the player at the Citadel, and Elder Lyons is nowhere to be found. On the Pip-Boy it says that "Take it Back!" and "Project Impurity" are not completed. Speaking to Elder Lyons by finding him doesn't work. A fix that worked for me was to open the console and then type:

player.placeatme 000156E4 This allowed Elder Lyons' script to be reset, and it completed "Take it Back!" and "Project Impurity" as well as giving me "Death From Above".
 * After the purifier is activated, if the player walks into the rotunda and tries to exit with the door it returns the message "The door is locked shut behind you. There is no exit". As if the purifier was not activated. On the pc you can leave the room by typing "player.coc megatonplayerhouse" or any other cell name to at least leave the room.
 * After the purifer is activated and the normal ending cutscene, the player stay lying on the ground and can't move. No cinematic or any movement of the player when using controls. Only a rale can be ear when clicking on E.
 * After Talking to Scribe Rothchild in the Citadel Lab, The Point Marker will appear in the middle of the left hall of the A-Ring, and there is no sight of Paladin Tristan.
 * When playing through the Satellite Relay Station in "Death From Above" Cross and the rest of the BoS members disappear. When in combat their voices can be heard but they do not aid in combat and are nowhere to be found. Fast traveling recovered Cross, and Paladin Tristan appeared back at the Citadel after completion of "Death from Above".
 * Cannot complete 'Death From Above' the BoS guys and Fawkes stop following half way through the satellite relay station, so need to continue alone. After download data and continue to exit to capitol wasteland, game load screen appears, but then just goes black, still with the overlay changing and the timer symbol just cycling around, but does not load. Have to Reboot system to continue, but this occurs every time so cannot exit the door.
 * When you beat the final chapter, the "2 weeks later" never appears, and the "Settings" menu, and downloads area, become "sticky" and glitchy.
 * After installation of Broken Steel Scribe Rothchild disappears after giving him a few Cameras. (Confirmed on Xbox 360)
 * After installation of Broken Steel unable to give Scribe Jameson Holotags. (Confirmed on Xbox 360)
 * After completing the final quest and talking to Elder Lyons about giving him supplies to rebuild Prime, he vanishes and is nowhere to be seen. Rothchild may vanish the same way.

Puppies glitches

 * After getting the Puppies! perk, there is a reported incident of no longer being able to hire any follower other than Dogmeat's Puppy, even if the puppy is dead or outside Vault 101.
 * If the player kills Dogmeat's Puppy, even accidentally, the puppies may stop respawning and the player still will not be able to add any other followers.

Follower glitches

 * After Sarah's "So much for celebrating" dialogue if Fawkes is told to enter the code, his dialogues are not heard, and when he enters the room, he just stands at a place until there is the explosion.
 * Star Paladin Cross refuses to follow you when she appears beside your hospital bed in the Citadel after you've completed Take It Back! After telling her to follow you she stays put, yet her dialogue options change as if she was following you. The only way to get around this bug in the console versions is to fire and re-hire her. That will make her follow you again, but this problem will resurface any time you tell her to wait in the future.. For the PC version, you can permanently fix this problem with the GECK. See the Discussion page for a step-by-step walkthrough of how to fix this bug by using the GECK.
 * When fast traveling to Megaton with a mind controlled deathclaw it will appear alongside you and will attempt to kill the inhabitants (and will most likely succeed).
 * Players may be stopped from activating Project Purity. Sarah Lyons becomes stuck on dialogue (when you choose not to kill col. Autumn) and does not initiate the dialogue choice of who should activate the purifier. Alternatively, if you do, she simply states "Let's make sure the control is secure before we do anything else," and will not continue. However, it is still possible to level up to level 30 and the improved enemies can still be found throughout the Wasteland.
 * Upon entering the purifier airlock at the end of Take it back, followers going in with the player in may vanish permanently after the "Two weeks later" cutscene.
 * All creature companions (Sergeant RL-3, Fawkes, and Dogmeat) are nearly invincible when first hired. They will still be the same if hired before downloading Broken Steel however.

Level up glitches

 * When level 20 reached the skill or perk screen never show up and the player stays at level 19 while his exp. Keeps rising past the max.
 * The game freezes upon reaching level 21, distributing skill points and picking a perk. Possible freeze occurring at lower levels on PC.
 * As the player levels throughout the extra ten levels their karma title will not change.
 * In the trophies section, the images for Messiah and True Mortal are switched.
 * After level up from 20 to 21 new chosen perk and skills are not saved while level does go up to 21.

Purified water glitches

 * When a NPC drinks FEV infected water (in combat, usually), you'll get the message "Continued consumption of FEV laced water will be fatal" as if you had drank it yourself.
 * After the Broken Steel DLC is installed, water in the basin remains irradiated.
 * Aqua Pura crates appear in front of Evergreen Mills, even though the Purifier hadn't been activated yet.

Liberty Prime's head

 * After finishing Death From Above, Liberty Prime's head will appear both outside the Satellite Relay Station and inside Citadel Lab.

Exploits

 * An exploit for unlimited BoS armor, holotags, Enclave armor, and weapons (including the occasional BoS Paladin equipped with a Tesla Cannon) during the initial assault on Adams AFB. Just before you cross onto the runway after the deathclaw cages, BoS and Enclave troops are seen battling behind the blue pulse repulsion field. You can then cross onto the runway and either kill or wait for the Enclave to kill the BoS troops to collect their items. However, the fallen bodies disappear after about 10 seconds. The troops will respawn when you cross through the wrecked hangar back towards the deathclaw cages. This can be repeated to your heart's desire.
 * After completing The Amazing Aqua Cura quest (and if the customers killed Griffon), his body will have a leveled amount of caps on him. In later levels, he will have 600, and in levels around the late 10s, he'll have around 200. But, after a day or so (in-game), the caps will reappear in his inventory. This glitch is very helpful, and it's recommended to do it every time you go in the Museum of History.
 * Dead NPCs throughout the game may disappear once Take it back! has been completed. One such involvement is all of the dead NPCs in Old Olney and the Old Olney sewers (Old Olney underground is not affected however). As a result, the Prototype Medic Power Armor can only be obtained before Broken Steel starts.
 * After adding Broken Steel, there is a marked increase in the number of times/places where Fawkes is "stuck," especially when walking through places where he is too big to fit and must crouch. Examples of this are in metro tunnels where the floor drops out and creates a path, or some places in Rivet City. This also happens at random points, where Fawkes will be stuck in a cliffside or rock cropping, partially exposed.  He will react to being spoken to but not react to your movements.  You can fast travel next to him or simply move to a different section of the building and he will be by your side again.
 * Adams Air Force Base map glitch (http://www.youtube.com/watch?v=bXtFfZDqD3w), walk outside the map on Xbox 360
