Kulemak Boss Invisible

Just did my first Kulemak's Invitation and after adding the 2nd modifier onto the ring the boss revived completely invisible. I was still able to kill it since you have infinite lives but not being able to see the powerful attacks coming or the effects thereof makes the fight just a "little" bit harder.

Having the same issue and I play on Hardcore so I can't actually kill him - not being able to see where the bosses are at all or what abilities they're casting is a big problem. Had the same issue on both DX12 and Vulkan, turned off Dynamic Culling

Same here. I was level 93 HC and decided I was way stronger than I needed to be and then after killing him once he went invisible and killed me. Talk about mad. I wish they could do something but I know that will never happen. Makes me not want to play any HC because of the bugs this season. It's a lot worse than normal I feel like.

It would be nice if the devs could address this or fix it soon. Really sucks not being able to play hardcore because of bugged bosses. Another bug is when you open an ogham legacy chest or whatever where the boss spawns back 5 times stronger each time, well he literally disappears and you can't finish it. Waited forever to find one and first one I find I kill him once and then it just keeps swirling above where he spawns and shows as not complete on my map. Come on devs fix these things please. Especially kulemak. One of the main farmable bosses is completely broken ..
