I was playing the mod and I noticed that the mod config for the % chance to succeed isn't rolled for each individual organ. It just does a check if you get all the organs (or the ones available from that corpse) or not. Would be nice if you could set the % harvest chance to be rolled for each organ. This way, you can still randomly get some organs, but not too many as to break the balance. It would also mean that higher quality doctors mean more organs harvested, but newer medics can still get some (instead of failing all the time).
