It's not really a bug as much as a possible oversight, but I got into an issue with the Goblin that resulted in the fight being unending. Goblin was fully erect, hero was on the ground and there was no bleeding. Goblin would always go for the rape and never went flaccid, so there was no escape. Even after taking a few tanker trucks full of goblin jizm, fight wouldn't end.
Appreciate the willingness of most enemies to rape when the opportunity presents itself and I know the Goblin's schtick is it's unending stick, but maybe after a dozen ejaculations can we get a reprieve so the fight has a chance to end?
