POE2 Rathbreaker fight bug

Apologies, as I did not grab a debug screen shot when this occurred. But, earlier today I got to Rathbreaker in act two for the first time. Not knowing the fight mechanics, I ran up the side of the cliff a bit just to bait him out. He initially started to come down the left path from the top of the cliff as hyena adds started spawning, but quickly turned around after casting one or two abilities that did not connect with me. When he got to the top of the cliff again, he just stood there frozen at a bit of an angle casting zero abilities and not moving an inch. Any time I did damage to him, it healed almost instantly so it was impossible to end the fight requiring a reset. I have not tried the fight again, but that definitely appeared to be a bugged fight.

I can reproduce this everytime, trying to run down from all hyenas he follows, than goes bac to the cliff edge and freezez unkillable, heals instantly.

I've got the same issue, he's just standing at the top of the cliff like you said not taking any damage. I was hoping someone had solved the issue but doesn't seem like it yet. Hoping this gets patched soon!

literally just happened to my alt, wouldent be so bad if his gp didnt regen quicker than we can dmg

Also for me hes bugged standing in the middle on top i dont know how to reset him

same problem here

same goes for me

same here. And how what?

To overcome this bug I died, then started to fight with the boss, killed him, and done... but it just worked after I died and started at the checkpoint

Same here. The bug is still not fixed ._.
