I was playing as usual when my drive port stopped to connect drives. It seems like port entity is gone. Reseting the whole thing or creating another game fixes this bug. 

How do I retreat drive port back to normal state? 

The same problem

Hello! sorry for being 17 days late... But if the drive sockets aren't connecting the drives then do the following: Get any drives away from any of the three sockets, save and reload your file and it should be fixed! The problems happens if a drive is near the drive socket while saving, it doesn't happen 100% of the time but still try to keep them away from the sockets :) .
