I have the mission to give Faust 4 limbs.  I've got one, but there doesn't seem to be any way to make him take it. 

Do I have to have all 4 to trigger him taking them?  That would be pretty frustrating given the time limit on limb spoilage.  If that's how it works it'd be good to modify the quest so you can give him limbs as you get them and the quest tracks how many you've turned it.

Anyway, thanks for the game, it brings together a lot of fun ideas and I'm looking forward to experimenting w/ the body part system.

P.S.  Do you have a system for uploading save files for bug reports?  I found an artifact "Fire of Claw" which won't display its stats but instead brings up the error box.

UPDATE:  Found that quest will complete if I have all 4 limbs when talking to him.  However, it didn't give me the opportunity to choose which limbs to give him.  I had more than 4, and it just gave him the first 4 in my inventory, which included a Living Stone Leg that I didn't want to give him.

SUGGESTION:  Allow the player to choose which limbs to give him so they don't inadvertently give Faust valuable limbs they're saving for themselves.  Also, allow the player to start turning in limbs even if they don't have 4. 

Yeah, that's on my TODO list. You need to give him 4 items with the "Replacement_Limb" tag, and all at once. It is the only quest of its kind right now, so I'm not too worried about fixing it just yet. It will be implemented at some point soon though.
