Duck and Cover

Okay I cant figure this out my main character will randomly lose up to 9 HP and he is not radiated is this some sort of bug or is something seriously wrong?

Did you take a Super Stimpack?

Thats the only thing I can think of right now that might make you lose HP.

Crap I completely forgot about that :oops: Besides I always kinda figured that, that part of the description never worked anyways huh I guess I learned something new thx
