I remember funny glitch. When i had Lidia as my wife, as i returned my home (lakeview manor) Lidia started moonwalking on stairs. She didn't go down or up, and her animation was looking as she was backing off. It was very funny, and i left my save with "moonwalking Lydia" if i ever want to see it again

Or when one day i was playing with console commands, i made tiny cute Odahviing, i sit on his back, and after a while i decided to make him bigger. I type setscale 10 while in air, and the game glitched as horribly as hell, i couldn't even saw land, and it was so laggy, tjat i decided to switch off and on my PC
