Diablo damage bug?


I was playing with diablo earlier and was doing really well, in the terror turn i killed off 4 people. In the end there were 3 of us left, and i killed them in the fights, but they didnt die? Is this a bug or is there something im missing? These were just the normal turns after that. I either did less damage than it told me during the fight or i didnt do damage at all but I ‘killed’ them both.

Thanks in advance

Similar thing happened here - I played against Galywix, who had 1 hp, in the terror round, beat him, but for unknown reasons he took 0 damage and survived. (Then killed me next turn)
