[POE2] A2 Cruel Rathbreaker stationary and unkillable bug.

Steps to produce bug:

1) Start Rathbreaker fight
2) Clear in a circle around the cliff while continuing to fire projectiles at him.
3) Drop his HP to 75% or lower.
4) Clear his adds again but I guess take one step too far to the start of the zone
5) Rathbreaker walks back up the hill, regens his life at about 2,500+ a second, ignores everything you do to him, spawns infinite new adds, stands stationary where he usually spawns, can be stunned-buildup knocked down but he gets right back up, regens back to full and just stands there. Since it's a boss fight you have to walk back to the checkpoint to re-instance it and walk all the way back. This one is a really annoying bug. I'm not sure why you guys would even make him like that in the first place, if you don't want players to backtrack to a safe place with 50 hyenas on them you should just put a wall up to limit the arena space.
