Ever since the line-of-sight (tm) changes I've been seeing a LOT of crashes in the EC that I swear seem to be elevation related. I can't count how many times I crashed going down the stairs in the sorcerer's dungeon. I crashed while running across the Pumpkin King's elevated platform soooo many times that I made a conscious effort never to step foot on it.
I've also had it happen in Destard and other places with uneven ground. I never crash on solid floors, roads, wilderness, etc. It's almost like the game can't see the next tile I'm supposed to be stepping on and says "eff u".
