I discovered a bug in a "cave" leading to a word of power place, the cave is called "Bonechill passage" it causes a CTD inside everytime no fail you can't even move and it just drops the game.
It looks really nice and cool in there for the 10 meters I've seen.
If Bethesda is reading and care to fix bugs, also worth mentioning the bug happens when you enter it from the north entrance when you go BACK from the ancient passage word wall, I actually came across that wall from above.

This might be a huge problem for me now to get out of that place cause I might not be able to back-track cause it might be to high to jump back up again.

So a word of warning to anyone going to enter bonechill passage.
