Gonna need a list of mods that might be affecting this; I get the feeling this is another furnace-related issue, similar to this one reported on Micro Machines, since they use nearly identical copy logic here, but so far, I haven't been able to recreate the issue, even after testing with several different overhaul mods.

It's not exactly feasible for me to locate and download every single one of those mods individually. I tested all of the ones that stood out to me, still can't reproduce the error.

You could try generating a save file without mini machines enabled, send that over in whatever way you can (google drive, onedrive, etc), then I can load it up with mini machines and see if I can trigger the error; then maybe I can narrow it down from there.
