I am finding that occasionally my frames will drop to 10-1 per second. I go over to my factory area to find the issue and see that me caretaker drones are clumped together into one square next to my digital storage unit. I lockdown the drones from the main unit and my game goes back to normal. But when I un-lockdown, the issue comes back as the drones clump into one square right next to the drone station. This issue is temporarily solved by exiting to OS and relaunching, but it happens again after 5-10 minutes.
