A DE friend of mine was trying to make me a R2 unit but she need 4 identical Control Units. She made them in her Factory, but neither of us could get the Control Units our of the crate the number would go down for a second them go back up to the original amount. Then I tried making a new schematic myself and the same thing happened. Both of us could retrieve things from out of our other crates and she could retrieve items from other crates made at that factory. Is this a known issue or something someone has encountered before?
