consistent crashing

jassibhappi​  I'd need a lastcrash with your Mods folder removed anyway.  If you still need help, please remove the folder and test again, and then try to attach the new lastcrash.  You'd need to delete its first line of text before the site would accept it.  Please also post a dxdiag.

I do want to note that your issue is different, in that the OP is only seeing crashing in the new world, which has been reported with some frequency.  Crashing in other worlds is probably not related to the new EP, although it could be; you could always disable the expansion and test in a new save if you're curious.
