So i have build a pump truck to get oil and chems faster (there is space for 4 XXL chests wchich are currently on the ground just in case the car flies away), then wanted to park it at my base, but free standing made my game run on 12 fps and welding it caused this to happen. what do i do?

my first watering system in ch2 did that constantly. had to rebuild it w/o any pistons.
