Bug reports (Spoilers ahoy!)

I just adventured in the Den of Danger. I found the halfling, who asked me to give him a health potion. I agreed and he took *all* of my health potions. Is that intentional?
Then I defeated the boss and retired, but the quest hasn't been fulfilled. Was I supposed to go see the halfling again?
EDIT: The second time I tried the quest, it was completed as expected.
