Possible solution for crashes (unrelated to resolution change between saved games).

i have installed all recommended mods, but the game usually crashes in mebbeth's house (when entering and exiting. only in mebbeth house, nowhere else

scientt i have no knowledge about hex editors, etc. what can you suggest otherwise?

Upload your exe someplace post link on here and give me resolution you're using with WS mod so I can manually patch it.

That happened to me too, but it doesn't affect the actual game, so I just dealt with it. It's annoying to have to restart the program every time, but after the crashes I just loaded the auto-save and I could enter Mebbeth's no problem. I also had some crazy visual glitches in Mebbeth's, but again they had no effect on the game.

i had the same, always crashed while leaving the house.
after a few tryouts i talked to mort, then i could leave and save a new game. i will never save in houses again =)
