Good feedback, I don't have comments for all of it right now.
Not so much a bug, but a suggestion. For the elf's ability to eat flesh, I disliked that I couldn't tell which body parts gave me powers. I know the mystery is part of the fun, but the limbs provide very very powerful health potions, but they could also give me abilities. I never actually did this, honestly, but this could promote quicksaving, eating the limb to see if it has powers, and then reloading if it doesn't. I know it is more the player's fault in that case, but the current unlabeled system somewhat promotes this save scummy behavior. Minor thing though.
Saving before eating a flesh part is fine, there's nothing wrong with it, and since you can eat the flesh at any time, there's no way at all to prevent saving before eating an item, except for an save system which only allows you to save and quit, which would be annoying for far too many other reasons.
It can't be exploited since the parts which have skills are pre-placed and fixed, there is no possibility to gain lots of skills by saving and eating the same part over and over until you get a skill. This is not in any way a thing which needs to be fixed to "prevent save-scumming".
