Currently the Blackheart dungeon lv 40-43 is bugged and I am curious if anyone has a solution. Specifically the Harpy boss that spits fire... start the fight fine, but when she is at approximately 50% health she goes invisible and is untargetable. I have tried the dungeon w/ 3 different groups, attempted the boss at least 10 times over the last week or so, and it always happens. Any ideas/any timetable on a fix devs?
