This mod can be added or removed at any time during gameplay. It might even be desync safe!
When you pick up an assembler building (as an example) it will give back circuits, wires, plates instead of the building.
If you pick up a blue belt, it will give you whatever your mod pack requires to make a blue belt. In vanilla, this would just give you back a blue belt, because it requires a fluid input. If I gave back just red belt and other items, it would technically be voiding some lubricant. no one wants that!
I might add an option to return fluids as barrelled items.
