Title, placing the cube in the vanilla or any modded chest that uses the vanilla linked-chest prototype causes the 'cant find cube' message to appear every few seconds until the cube is removed again. Mods I understand can add compatibility for item teleporting or cube ownership, but I'd expect a vanilla prototype to just work. Discovered via Unichest, tested with unichest, creative mod linked chest, editor extensions linked chest, and vanilla linked chest.
