Occasionally when I take damage, it seems like I pick up a persistent debuff of some kind that causes me to take a point of damage whenever my health fills up. This keeps my health constantly at less than full, meaning my food is constantly draining. The debuff does not show up as an effect the way things like poison or hunger do, and does not clear when I drink milk or use items that are intended to remove negative status conditions. Moreover, it appears to be permanent, and will last until my next death.

I have no idea where it's coming from and no leads to go on, I just know that I've never experienced it outside of this pack.
