Since the 0.9.0 update I have not been able to complete a dungeon. I have tried 3-4 keys of both lightless arbor and soulfire bastion. I can go through the first zones, choose the different doors i want, and get to the penultimate room. But there is never a door to the boss. In the pictures you can see one picture where I am in the final room with no door open to the boss. In the other photo you can see that after waypointing out I still have the soul embers and kindling stuff on my buff bar even in monos. The mono screenshot was on .9.0 and the screenshot from soulfire bastion is from earlier today on .9.0b
I have been able to do the fight when in a party with players for who the dungeons isn’t bugged, but I’ve had plenty of portal bugs there ( twice I got zoned to a different area and got stuck in a wall, but it seems to be the soulfire dungeon area) and once we got zoned to the starting area where a player was just starting out fresh ( and was not in our part)
afterwards it was still bugged for me solo. will try again later once I found some new keys. (I did a steam file verification and see if it helps)
Happened in Solo Online Play and in a Party for me. I have tried doing 5 dungeons so far. 3 Lightless Arbors all had the same problem, but only for my Character. My 2 other buddies in the party did not get the bug. Then I did 2 solo Soulfire Bastions. The first one bugged out like @Apklittledog, and the Second one I got the bugged Boss Door.
Also playing a Lich if that has something to do with it as well.
Okay I’ve found a “kind of but not quite” solution
I’ve just encountered the bug that the final boss door is selectable but won’t open. I pressed T to open portal to go back to town, and then I could use the portal again to go back to soulfire bastion, but when I loaded in, the graphics were all messed up, I was teleported to somewhere beneath the arena.
So I used a movement skill and I was levitated to the arena, I killed the boss successfully, but the soul vendor doesn’t have anything in its inventory for me to gamble. So I still didn’t get any rewards.
TLDR: teleport back to town and back to soulfire bastion, into a pile of graphic mess, used movement skill to go back to arena, killed boss, but nothing to gamble.
