As the title says, the Haldain Lumber Camp delve boss refuses to respawn no matter how long I wait. This has been a thing for the past few month, but I was hoping it would get resolved on its own eventually. Every now and again, about once a week, I'd go in and go to where I know the boss spawns, and it is nowhere to be seen. I wait for an upwards of an hour and still no respawn. This happens every time to me. For the record, I had managed to kill the boss and get the achievement already before encountering this bug, I simply keep going back in an attempt to try and unlock the Wildburn skill style.
