I don't know because I didn't look at how exactly the glitch works. I remember people saying the first duping glitch only worked with placeable items, but I'm not sure if it's still the case this time. As fish bait is a 1x1 item, and I don't have confirmation on how exactly the glitch works, I'm halting and avoiding trades.
Ahh, gotcha, that’s understandable, then! I’m not 100% sure either so I get wanting to be careful for now.
I just tried it and it didn't work with bait. In fact, it actually deleted 9 baits out of my 10 stack. I reset obviously. I know it also doesn't work with clothing, diys, nmt, material, fruits, etc.
I think it requires furniture - stuff you can't walk through.
