Um try running it from the terminal and see if you get any useful output?
Please explain. I get the principal, but what commands should I use?
Also, I forgot to mention that it changes whenever you move. You might be part you, part rat, then you turn into a furnace. It's like you're stealing bodyparts from other characters in-game. I tested it with an older character of mine, and his chestplate was on some dwarf woman and shook around in conjunction with me walking.
Any ideas? I'm gonna try reinstalling the game.
In the meantime, here's another picture for your enjoyment:
