With this cheat method you could convert bronze to osmium (ore/bars kelp/essence) -or- you could use it to convert base quality crops/fish/bugs/etc. of one type into osmium quality of any other crop/fish/bug/etc of a completely different type.
For instance, you could turn a stack of Bronze Ore into a stack of Osmium Bars, or you could turn a stack of base quality Tuna into a stack of Osmium Cactus.
This cheat seems a bit too OP to be explained in public and I would imagine you would prefer to patch it without anyone knowing about it. Is there someone I can talk to in private to explain this issue?
