Suspicious collection

Exploration Stage: Stained-Glass Mezzanine
From: Detective
Description: Is it possible that the loft residents stole the bees? Because it seems like he had a hobby of collecting insects. There were framed insects on the wall. An avid collector will go to any lengths to acquire rare insects. Let's see if we can find any missing bees in his collection.
Completed: That's a huge collection. And these bugs don't seem to belong to this city. I wonder where the residents of this place got these bugs from. There doesn't seem to be any golden bees in the collection. If they had it, they would have it on their wall as a valuable trophy. Or maybe they have it hidden somewhere?
