On the Overseer reward when I accept the reward "Overseer Collection item" and it moves to my overall quest reward screen, it then shows up in the tab as "Overseer Ornamentation Dispenser" but will still show the correct items to choose from (any collectable from the list of expansions). Once I have selected the expansion I want the collection from it will show <insert expansion here>Collection item again
This has been noted in at least one other bug report and one of the Test Update threads. A dev has responded so they know about this.
