Playing a sandbox and when I get my 2nd Cargo Hold, everything seems to be working ok... but as soon as I add my 3rd, everything stops working correctly. Several droids just backed up with boxes and the cargo hold is wide open. Seems like only 1 is working correctly when I have 3. I tried boxing up the 3rd one, and the same thing is now happening with the 2nd cargo hold. Not sure if this is just a game issue that is unavoidable? Or is there a fix for this?
Most of my cargo holds are very close to the 2 factories I have. I rarely spread them out, but not sure if that matters.

Thanks
