Dead Money bugs

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.

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.
