301. Make it so storage-type furniture item stacking is handled differently; currently, if a cardboard box was spawned as part of a stack (as one crate on top of another, that is), it will not only be impossible to put it on top of another cardboard box or a crate, but also to just put it on the floor/ground, leading to them hovering in the air.
