Hello everyone, This night we discovered an insane bug in Dark Core instance in 4th Boss. As you already know, if you cant kill Xanthus Boss last boss will appear in boss room and wipe out your whole party. But this time some crazy stuff happened. When last boss appeared in boss room, Xanthus boss was at like 1% HP left. We killed Xanthus boss but last boss was still there. I thought last boss would disappear also a few seconds later. But he never did. So, we had to kill this boss also. We killed him and cleared instance untill last boss. And guess what happened ? Last boss was still there ! So, we killed Dark Core 2 times in same instance. I think something like this never happened before in this server.
And this is the last boss as usual
Edit : I hope you give all people in this raid some reward coins for discovering this bug.
