Tell me about it, I just had 50 hours of work down the drain. Never had any big issues before the patch, my game froze 2 times. After the patch, I'm fighting some DeathClaws and my game freezes, start it back up and go to load, and it says "This save relies on DLC which is no longer available........ect" and no matter what I do I can't load my game. What pisses me off is I don't even have any DLC for this game and I'm getting that message. This is the last Fallout game I will EVER purchase, no more $$$ for them, they are getting rentals in the future.
