Possible bug with regards to berserk

After having fought a paladin I seemed unable to get the healing benefit of berserk. The hit dam bonuses were still given. I have not experienced this behaviour with berserk before, I don't know whether it is a bug or not. I was in the middle of some fighting, so I don't have complete logs but here are some snippets: >>> 700hp 277m 805mv 8910tnl 6 PM water aff You are affected by: Spell: 'protection from good' for 19 hours.
