Steps:
1. Completed the Breaking Brick Mountains Level 7 collaboration quest in 2021.
2. Owns the minion (Wind-up Brickman) and King Slime Crown. Cannot find the Thug Mug item anywhere - not via isearch and looking manually. It was not on retainers, armoury, inventory, or armoire. I figured my little sprout self threw it away because it was ugly, not knowing that I can store it in the armoire.
3. On picking up the quest from the quest NPC Havak Alvak I get the notification "This quest has already been completed. You will not receive a reward." So I think I can just go buy the Thug Mug from the Recompense Officer...
4. However, checking with the Recompense Officer under "Other Seasonal Event Items" the "Thug Mug" item does not show.
5. Testing this with a slightly newer alt character, he had the King Slime Crown but not the minion or Thug Mug, his quest was not marked as completed and I was able to see the Thug Mug item on the Recompense Officer after completing the quest this time. So why can't my first character see this item?

Fixed it by:
Re-running the quest anyway. After doing so, the Thug Mug item appeared in my Recompense Officer list.
So if anyone else has this problem, try redoing the quest anyway and then check your Recompense Officer again.
But this is clearly a bug.

Windows PC but also n/a as this is clearly Server Side and only affects my oldest main character, not my alts.
