Ran into two issues with my late night run last night in Kara Crypts that happened AGAIN today, please fix blizzard!
-Kharon boss cannot be spawned. We cleared all trash and bosses before him (even talked to the NPC mini boss in the hidden room) and still the book around the green area in that room is not clickable and can’t spawn him!
-The burning webs from the spider boss room are able to go through the wall in Kharon room in different parts of the room you can the burning webs debuff, please fix so they don’t expand out of the spider room, but this is just a minor request, please fix Kharon ASAP to be able to spawn him again, missed out on loot twice now

Just came here for the same issue first noted, 2nd issue also happened to us. We killed all the bosses except the dark rider ( the 2nd closest choose boss to the entrance, the opera but we did wipe once, then we dropped to the spider boss, then the marrowgar reskin) We did the warlock boss and the engineer event but nothing changed when we did. We couldnt do the rider after because our tank deleted one of the objects to make space (after trying to get to the lich), we even went to the large room outside opera and killed all the larger enemies to be sure, as far as I know we did everything but kill the Dark Rider and kill every single trash mob in the instance. Anyway this seems bugged or something is very much not clear about how to summon the lich now.
Do not enter the secret room before killing Kharon. It bugged it for us.
My group hit the Kharon Book bug for a 2nd time and we believe we’ve found what is causing it. We freed Barian Maryla, and Sairuh Maryla did not die as scripted. Instead she was sitting and standing in a corner over and over, even after we killed Barian.
We later noticed in the room for Kharon there are 3 altars that correspond to the Harbinger of Sin, Creeping Malison, and the Apprentices, you can tell by the trappings near them. The altars Malison and Sin were both lit up, the one for apprentices was not.
We will not be picking Barian going forward, as we had no issues with Kharon spawning, after picking either other apprentice to kill.
Did you kill the third crept dweller in the last area of the dark rider room that patrols between Barian’s cage and around the boulder rock? All three crept dwellers in kara crypts have to die too and some groups do miss that one on that side of the room, also the one on the stairwell if you don’t go down that side of the stairs where another one patrols. HOWEVER, I can confirm a week ago we did kill all three and ran into same issue, but haven’t since then, so it’s strange some grps still run into this. I wonder if a possibility is maybe a group gets layered WITHIN the instance and that messes with it?
Btw, we did free Barian just in my run today and same yesterday and had no issues. The female NPC isn’t supposed to die. Before they hotfixed it, you could kill the wardon, get a key, run out, reset, and then kill him again for a 2nd key. Then you’d free and kill either of the male, and then free and kill the female npc for extra loot (like I said, this was fixed and no longer works that way). So it doesn’t matter which male you kill, she will still be in her cage unless you pick her.
Confimed that Crypt Dwellers are NOT related to spawning, but yes we went back and killed them.
