I was in the middle of a BGRIV game when I got the TO crash at the end of turn 86. I find that if I install the new (March) patch without BGRIV and replay from turn 84, which is before the TO emergence, there is no crash. But if I also install the new version of BGRIV which came with the new patch, the game crashes again at the end of turn 86 when the TO comes up, just as it did before. I've tried installing BGRIV without the world or text folders, just the misc data files (just to see if I could get it to work) yet the game still crashes when the TO comes up at the end of turn 86. I would just start a new early campaign game, but now I am concerned that with BGRIV the TO crash may still persist. Any ideas?
