I don't know how this happened. I downloaded the latest patch and now the Bunker is locked, I have the quest, I can access level 35 and I have the radio broadcast. I just cannot start the main adventure. I've tried reinstalling it on my xbox hard-drive, deleting the patch (just froze so I got it back) and pretty much anything one could do to fix something on their end. So it has to be an issue with the game itself. Is a patch in progress for this?

I'm on the same boat I have to different saves one I can't enter the BOS Bunker at all and in the other I have a glitched character that refuses to move to continue the mission.

For me it freezes whenever i try to load the bunker, I had not done the DLC yet but had been using the bunker for storage

@Toxikill : Try to finish some Quest in a different location, then try to enter the Bunker again.

@Blatherscythe : If you still got one savegame before you apply the patch 1.4 (i hope u do)

Try this :
Remove the Update 1.4
Move ur savegames to an USB or memory card.
Apply ur savegame from before the Update 1.4
Now play Dead Money (make sure u free GOD from the Cell, he is not buggy)
and DON′T APPLY the new update 1.4 while doing DM!!!!!!!
After returning to the Mojave, move to your Safe House and Save your game.
Now install the New Patch 1.4
Then Download Honest Hearts if YOU wish.
