Since HoT released I’ve tried to do arah p2 3 times and all of them were stopped at Operative Belka (literally the first boss) and she’s just porting around, the bone wall is up for some reason & the burning barriers are also active. I get that Anet doesn’t care about dungeons any more at all but this is pretty silly. I love solo/duo’ing Arah just for the sake of doing the dungeon, being stopped by a bug that completely halts a path of the dungeon and will probably not be touched for a few months is kinda defeating.
PS. I heard you can run to the bonewall at the far end of the fight, I’ve tried it twice but sadly no luck, might work for someone else though.
