So I've been playing for close to 100 hours with no problems other than some minor lag. All of a sudden, I can't activate any levers or anything. I can still pick up items, loot corpses, etc, but I can't activate any levers, mine ores and my followers say they will join me, but they don't. This same thing happened before, and the only way I fixed it was to reload an older saved game. But it just happened again in a different spot. I don't really want to go back to the same saved game I did last time because I will lose several hours of gameplay. I'm stuck!

I would just restart your ps3.

I tried that, doesn't work. =(
