Dead Money bugs

Exploitable bugs

 * 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), 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. (Other console verification needed.)

General bugs

 * 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 the DLC with the game, even when restarting the game or the console. You need to download it from the Xbox Dashboard and wait for the download to complete, then start the game.
 * Profiles on the same HDD other than the one who bought it won't be able to access the DLC. The game will give them 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, then switch to your own profile.
 * If you download the DLC and then delete it before reaching level 30, but after receiving the "Dead Money loaded" message, installing it again will reset the level-cap to 30, with no known way to fix it. You'll just have to start a new character, or play as level 30 instead of 35.
 * If the player saves the game while inside of a toxic cloud, it is possible for him to continue taking damage from the cloud even after leaving it, and even after returning to the Mojave after completing the DLC.
 * 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.
 * After finishing the DLC, going through the gate to leave may cause the game to freeze.
 * 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.
 * If you finish Dead Money with your internet on, and your internet goes off and you play, you may get Dead money's beginning quest offered again.
 * If you have a large save file consisting of ~10MB or more, the game may slow down to a crawl while you are near the main fountain in the Villa. This can sometimes be fixed temporary by saving and reloading but will get worse as you progress through the story.
 * 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.
 * when trying to go into the abandoned bos bunker it will be locked and require a key but there is no key and reload a recent save will not fix the problem.

Item bugs
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, non-player characters will still use ammunition, and it can still be repaired with miniguns.
