I've had items get stuck inside the table when assembling, but I've always been able to use rotate to free them (tugging doesn't work nearly as well as just rotating the item until it's out of what it's stuck in). I've never had the "ghost" of any object appear in my game. Have you been able to come up with a consistent method to produce the ghosting bug? I'd like to see if I can replicate it.
the ghost part only happen if you are able to sell the item after it gets stuck in the air. and the stuck in the air bit just happens when dropping, rotating or flinging items. also make a tin item and sell it, it will sell as copper. I will upload a video where the floating bug and the gamma bug happens
