I Began the quest from quest giver:landenel
I went to the location of the brownie brush
I used the potion to weaken the agaric flies that spawned and killed them.
I looted the brownie brush that spawned.
I went back to quest giver Landenel
Landenel has the green checkbox inside the main story icon over his head.
Duty list confirms next step in quest is to: Present Brownie Brush to Landenel
Problem: When I interact with Landenel all he says it "I pray this year's brownie brushes comes late..." with no option to hand over the Brownie brushes.

Things to note: Brownie brushes are nowhere in my inventory (I did not sell them, move them, or any funny business)

I went back to the original area of the brownie brushes to recollect, no luck

I can not abandon the quest to restart it, I already looked into this.

Between collecting brownie brushes and running to NPC quest item is not in inventory. Item did appear on screen as collected and quest updated to next step of turn in.
