Dead Money bugs

Multi-platform

 * If you have completed Dead Money on one save file and start a new game with Dead Money on the new save, it is possible that after you wake up and finish speaking to Elijah the gate that leads back to the Mojave Wasteland and return to the bunker.
 * If the player saves the game while inside of a toxic cloud, it is possible for to continue taking damage from the cloud even after leaving it, and even after completing the DLC and retuning to the Mojave.
 * If you do not recruit Dog/God first, when you eventually return to the fountain with the three companions, Elijah may still ask where everybody is, making progress impossible.
 * Possible fix: Using the Gamebryo console commands on PC, and there is a patch for Xbox 360 (re-downloading the DLC might not work). For this you need to install the patch just after entering the Abandoned bunker. If you have the Ultimate edition version of New Vegas, you can install the patch every time it is required if it's been deleted to fix other problems related with the system cache.
 * Dead Money overrides some of the changes that have been made to the grenade launcher in previous patches. With Dead Money installed and nothing else taking up space in your load order, the grenade's base damage is increased to 30, its spread is increased to 1.0. NPC's will still use ammunition and it can still be repaired with miniguns.

PC only

 * On occasion, the DLC may crash completely disabling the Dead Money add on. All of the perks remain, however any Dead Money items that you pick up will come up with a giant red and white diamond instead and you are unable to retrieve the item. Take note that this problem does not happen on any other DLC.
 * Although dialogue hints to shoot at Ghost Seeker's gas bombs, it is not possible even with 95% V.A.T.S. attack probability.
 * The game may crash right after the initial speech at the Villa. If you have adjusted the timescale, you will need to load a save prior to the Villa and return the timescale to its default of 20. Do not readjust the timescale until after Elijah's initial speech is concluded and the hologram returns to its normal state. Another work-around in preventing crashes is by entering the Divide and then leaving again before traveling to the Abandoned bunker. If neither of these solutions works, it may be necessary to disable all Dead Money files, all mods, and delete everything named Dead Money in your F:NV Data folder. Then install the add-on again and before entering the bunker, save three different time and do not save while in the bunker (not even quicksave, autosave is ok.).

PS3 only

 * If you download the DLC and then delete it before reaching level 30, but do this after receiving the "Dead Money loaded" message, installing it again will reset the level-cap to 30. The only work around is to start a new character or continue playing at level 30.
 * If you have a large save file consisting of 10MB or more, the game may slow down considerably while you are near the main fountain in the Villa. This can sometimes be fixed temporarily by saving and reloading but it will get worse as you progress through the story.
 * There is a particularly painful problem of localization if you are in Belgium; the download you get is not the FR version but the UK version. This makes it impossible to play the DLC, as the game does not recognize your version.

Xbox 360 only

 * There is a way to leave the Sierra Madre vault with all 37 gold bars. The player must have an abundance of C-4, gas bombs, or demolition charges and place them in front of the shield door where Elijah confronts the player in the vault. Then the player must grab everything in the vault and then talk to Elijah from the holographic projector. Convince him to fight then run (walk) out of the vault with everything and press up against the shield door where the charges are placed. Destroy one of his turrets (having Christine on your side will help), then he will then open the shield door (make sure you're walking into the door). You will phase through and fall but will get back up on the opposite side of the door near the exit. The charges should go off and kill Elijah and you will complete the quest and be able to escape with over a minute to spare along with all the loot in the vault. {Verify|01:00, December 13, 2013 (UTC)}}
 * If the quest ED-E My Love is not completed before beginning the DLC, upon the player's return the quest will have disappeared and ED-E will be hostile.
 * Downloading the DLC from within the game will not register, even when restarting the game or the console. You need to download it from the Xbox Dashboard and wait for the download to complete and then start the game.
 * Profiles on the same HDD other than the one who bought the DLC won't be able to access it. The game will show a message about the DLC being corrupt even though it is not. The solution is to sign into the purchaser's profile from the dashboard, then load the game and then switch to your own profile.
 * If you finish Dead Money with your internet on, and your internet goes off while you play, you may get Dead money's beginning quest offered again.
 * If you start the DLC while connected to the internet then try to load your save file without an internet connection, it could corrupt the DLC only with that save file and cause the effects above.
 * After completing the DLC, the gate that leads to the Mojave wasteland is locked and requires a key. How ever a simple reload of a recent save will fix this.
 * After completing the DLC, going through the gate to leave may cause the game to freeze.
