Thank you, I will get to that bug at some point. It doesn't seem as big atm because it is really just a sub optimal strategy for the player.
But I plan on locking off bones unless the player has beaten the current bone. That alone should make it less of an issue too because the player will have to build up healing strength before getting to a high-level bone. and by that point, the player could just one click weak bones.
(edit) Oh but that part about shared health is annoying and unintended
