Yeah, well, I'm currently crashing every time I try to enter the Neuromod Division for that one late-game side quest. It's a common bug that was never fixed; the only workaround is to replace the saved game's map file of the Neuromod Division with a file from an earlier save, or a new game save. I've had five or six crashes over the course of the game, as well as various slowdowns that occur if you spend a lot of time in one level (worst was in the reactor, also a very common problem) that you have to reload from the main menu or restart the game to clear, but this one's a showstopper.
Joy. Honestly, at this point I might just read a synopsis/watch the endings on YouTube. It was a great ride while it lasted.
