Mine (lately, ecpecially with the private beta) crashes towards the end of the game...When me and my enemy are locked in mortal combat (with me on top ). After that, it doesn't stop crashing, so I give up the level.
Before, it was a system crash, and the grphics card was blamed, now (with the card updated), the game.dat's blamed.
It happens when Dragoth is swooping in on Ranger's, Isengard planting mines, all sorts of things that have nothing to do with crashing.
I've been having problems like this as well along with a crash that occurs whenever I try to start a campaign. The game crashes and blames some error involving Gwahir.
