Somehow my main character was pushed into graphics near the Markarth wayshrine in The Reach, most likely by a wandering NPC or a guard. Now the character is constantly flickering on the screen because the game can't really determine the character's position yet keeps trying to do so. Trying to teleport somewhere or typing /stuck doesn't help because the character is kicked from the server after mere seconds for excessive messaging.

The ticket number is 240901-003413 - just in case this helps.
