When I built the station of jet suits and Duplicants began to use it, the game freeze(frame rate drops, not full freeze). It looks like this - the cycle starts, the game works fine - Duplicants wake up and go to work. When they go beyond the base in jet suits - the game begins freeze terribly. When the cycle ends and the Duplicants return to base, the friezes end too. If I close access to jet suits - everything works fine.
Just load my save file and allow use jet suits at the top of the base. For clarity, you can send them to kill creatures, so it slows down even more.
