Bonechill Passage:

this dungeon is really buggy, when you enter the dungeon at first glanse it looks ok, but then when you move in a little bit it will start to crach, as a stubborn tester (work related damage ) i
went inside, after a few crashes i noticed a spot close to the ice pillar there is a small hole, when you step inside it you will crash 100%, few crashes later i managed to get through the dungeon.

on the way back the dungeon will crash almost instantly, and its near imposible to get back again.

The same happens to me. I'm completely unable to pass through Bonechill Passage, because the game kicks me to the desktop.

Some people is saying that playing that part of the game in windowed mode solves the issue - I haven't tried it yet -, but it should be treated as a bug. I really like that cave and this bug is spoiling it.
