ok well its not that important but is still a bug(or a feature lol).if you are trying to make slave copy of a master key,the rocks need to be in your inventory or have an empty slot.if the rocks are on your backpack and your inventory is full they they will disappear. it will show the crafting,the rock disappears and all but wont give you any key.
Eddit:Please close it seems it was placing them on empty key rings,so not a bug
