Please Mods could you explain this to players,better than I am doing.
I have neighbors who don't understand ,how I work their facilities twice a day.
I tell them I go by the clock,and try my best to explain.
You have to have a stopping time.Stop,do no more for 8 hours. You can do others facilities over again.Even if it has been 8 hrs or less ,since you did them!
Go by the clock,and don't do any until it says you can. Whew!
