Yep, same thing with me after my save of 36 hours and its on BOTH my auto and regular save... so I have to revert back to my one save at 9 hours....
Its pretty bad glitch, and I doubt that a patch will even be able to fix the corrupt file save now... ,so either way, you will have to start up the most recent save that works, or start all over, because the games technical flaws and horrible bugs.
After what I have been through in my 50+ hours of play, I feel i will never buy another Obsidian developed game, and any Bethesda published game, I will make sure to read tons of reviews making sure it is bug free on their next game, if they are still in business, that is.
Yeah, I know what you mean! I like the fallout games very much, but all the glitches, and freezes just keep getting more annoying.
I can't even get to the strip anymore, everytime I go through the entrance, the game keeps freezing.
I threw my controller all over the room out of anger.
Hope bethesda comes with a patch very soon, because they scare customers this way..
