Since the Patch my Foli's health is messed up. His health bar permanently degrades overtime and cannot be healed over a certain amount. This gets worse and worse and is especially noticeable in CB where his health bar eventually won't heal above 10% of his max. I'm not 100% sure if it's graphical or his health is actually gone. I see other people claiming his leech is the problem but my  Apoth is unable to heal him either.
