At some point something happened to Tekehu.  He is now invisible and level 0.  Unable to be used in combat or level up.  He's invisible in game, in the inventory screen, and on the ship.  In combat he simply shows all errors around him and no speels are available since he's level 0.  I've tried reloading saves, verifying files, re-installing the game, etc and nothing works.  I didn't notice this right away as I move him in and out so I have no saves from before.  Just looking for any ideas on what the heck is going on here. 

Did you find why Tekehu was like that?
