This is the only area associated with 2.5 where I've been having this problem routinely (although I did crash once in Urth's Font and when accessing the cutscene with Ellie in "Her Final Vow").

ETA: Just attempted to run Amdapor Keep HM with some friends, we managed to make it past the first boss, then just as I thought I might be in the clear, I froze and crashed again, and couldn't get back in until they vote-abandoned and it kicked me out to our FC house.

I spent a while yesterday updating drivers and whatnot and I still got the error. One time like you I made it into the first boss room and I was sooo excited but I still crashed. Beginning to think it might be a corrupted game file?
