Eh, there is one puzzle that I can't solve, though it's because my game glitched out, I'm sure. It's in a cave called Falgunthor or something like that, and there are 4 gates and 4 levers. My game messed up so that I can't open it, so I'm sad about that. It was part of a quest too, so double sadface.
There's only one "lever" to this puzzle, and it's actually a chain.... 2 doors open and 2 others close, you just pull it once and walk on (then stop and wait an hour so Lydia can travel through the wall to catch up)..............
Only time I've been stuck on a puzzle is because I'm dumb and didn't see a pressure plate or missed a chain/lever earlier on in the dungeon.
