Assist is somehow bugged

<617(67%)hp 361(37%)m 100%mv 311tnl 9 AM wilderness> You assist Sarsett against Yorhitoth the Master Slaver. A duergar dodges your claw. Your claw *** DEMOLISHES *** a duergar! A duergar dodges your claw. A duergar parries your claw. Seizing on your instincts of the predator, you strike swiftly at a vulnerable point! Your claw *** DEMOLISHES *** a duergar! A silverback gorilla's punch *** DEMOLISHES *** Yorhitoth the Master Slaver! A silverback gorilla's punch *** DEMOLISHES *** Yorhitoth the Master Slaver! You dodge a duergar's punch. A duergar's punch DISMEMBERS you! A duergar has a few scratches. As you can see, using assist made me attack a mob that wasn't involved in the combat at all. ...maybe the mobs should be censored, with it being an explore area?
