I did a search in case this was already being discussed and found nothing related to my issue. I've tried to complete the Return to Long Live the Lich several times now and each time I get into the Joko fight he disappears and never returns, but the room is filled with scarabs and the flaming floor is still active.. The first 2 times it was bugged I had DX11 enabled, so I disabled it and tried again to no avail. The map chat in Kourna also included other people saying the game crashed either during or right after the Joko fight, before the story completed.
