yes, after using minor potion to restore to full HP, I got some hits from skeleton archer, but after 3 turns I lost all gained HP back down to the HP before using the potion and because I was hit in this turn my char died and she was never poisoned nor burning
Generally when you get hit, you take damage. Health potions are a one-use item. They heal you when taken and then they stop. That might have changed in this patch since the potion icon persists, but you losing health after taking damage makes it hard to determine if it actually is some kind of bug.
Personally, I think nothing is wrong and you just were shot normally and died in the expected way when several enemies focus fire on you.
