I have a character that is stuck inside a stone wall in Cyrodiil. The /unstuck option to teleport to a safe location crashes the client to login. The character "times out" and crashes the client to login. This was caused by the knockback component on attacks that causes the character being knocked back or staggered backwards to ignore object collision.
A help ticket to move my character that's currently unplayable is going onto the 9th hour.
