I thought the human BD issue was the cause of the hell load of extensions during the patch two weeks ago? It was fixed before the hotfix patch last week as far as I'm aware.
But yeah.. 1P dungeons were fixed last week.. Aeria derps please.
Honestly though the devs/gms need a kick up the ass.. I still say any bugs that put a critical stop to the client should be addressed and fixed asap, even if said client nuke is avoidable in monster arena by just removing the weapon. That's besides the point.
