New town arranging is great but

The new update with the new way to move stuff was good but you could only save it when you placed down all your buildings. When you are lvl 30+ and you have like hundreds of buildings it starts to get tedious. Also when I get close to finishing my town a glitch always happens and when I place a research building another same research building shows up even though you can only have one of them. When I try to put down that second building the game gliched and it restarts my game and my town wasnt saved. One way to fix this is probably a way to save your town before all buildings are down and you only use that town when its finished. Thanks
