Quest bugged out?

[OrangWuTang91]

So I've basically played everything the game offers me through quests except for the last undead dungeon. However the quest for the undead NPC (collector?) seems to be stuck or bugged. I played the second undead dungeon three times now but the quest is not progessing...

Am I doing something wrong or is this a bug? My guess is the latter because I know that there is a quest for a laboratory which my friends and I have in another world and which I didnt have in my own world yet. Im guessing that quest gets triggered once the collector quest is progessing?

Two screenshots which show that the quest is stuck even though I have those plasma collectors already:

After trying several things I finally found out how to solve it. So for those who are stuck with other Hollow Halls Quests:

First of all I can comfirm this is just a bug and you didnt miss something.

All I had to do is make a brand new character, enter the halls and the Quest was automatically completed.

Also when I entered my world with the brand new character the NPCs had all Quests available again (finding their items). You can then just accept all the quests they offer, log into the same world again with main char and he will then have the missing quests too (in my case the alchemy guy quests which were missing before).

Long story short - Making a new character and logging into that world solved all of my problems/bugs.
