My character got stuck in a tent in one dungeon. I was doing some quest in some dungeon, I saw a monster in a tent, I went to kill the monster, I killed it but in the process I accidentally went in the tent. When I tried to get out of the tent, I discovered that my hero cant move past its entrance. I tried to Whirlwind out of the tent, but without any success. There was a bed in the tent, so I went to sleep (hoping that it will fix the glitch) but things get worse - my save was overridden and my 3 last saves now are in the tent (stuck). I'm not outdoors, and I cannot fast travel from there. I can't only load my hero from a previous save (which is 5 levels lower).
Is there a cheat for going through walls, or any other kind of getting out of the tent?
