Placed some dogfish on a couple of drying racks, and at some point I came back and the racks appeared to be empty, but nothing could be placed in them and inspecting them gave the quote for something still drying on them. The drying dogfish sprites were there when I first put them up. Used "print(TheInput:GetWorldEntityUnderMouse().components.dryer.ingredient)" to check, and the dogfish are still there. Screenshot.
