Not a Bug Jay's curiosity subquest bug

Hello i've been doing the quest Jay's curiosity and I have a problem with it. I've done the 3 subquests of gwin, the rememberer and grendel tha really old but I cannot seem to start the subquest of bruce which I have to do in order to finish the quest Jay's curiosity. Can someone help me out here, maybe I did something wrong?

 

But i already have bob's shell in my inventory?

 

It does but I alrdy finished that subquest. I have done all of them except the one from bruce and that one I cannot start

 

Really? It doesn't say so on hidden-street >.<

 

I dont know whether I should make a new topic about this but I found out that I cannot start the quest 'I need to find my daughter'. I did finish the quest 'the reason behind the mushroom studies' and according to hidden-street that one was the only pre-requisity... I haven't been to Ayan yet but the quest is in none of my quest tabs and Bruce has no lightbulb or reading mark above his head. It might be that I started the quest 'I need to find my daughter' and that I dropped the toy sword I need for the quest afterwards and I removed the quest from my quest tab and after which it didnt re-appear in my 'available' questtab, but I can't remember doing that.
Oh and I still cannot finish Jay's curiosity, I've tried dropping the shell and then getting a new one but it just didn't work.

 

Alright thanks for helping me, I've finished the quest. I had to do the quest 'stump horror story' and the quest of finding bruce's daughter before I could start the subquest of Bruce. I do still have a question though and I have it with most of my quests. When I finish a quest by giving the npc a quest item I either get the quest item back or the quest item won't disappear from my inventory, is this already known and is it supposed to be like this?
