I was placing an XP Vacuum up by my farm, cracking open the dark room to just make sure nothing had mysteriously stopped working, and found this in there. Now, it does still function, judging by the loot arriving down at my base when I check, but I felt I'd bring this to your attention just in case.

Soooo, what part of your build has something to do with random things? Is there an Item Collector?

Yea, it's above the room, sorry for not specifying. It's collecting them just fine, but I think it's starting to cause lag due to building up.
