On 2 different saves/worlds now, I have built up from scratch and got to the point where it was time to try building a car. I'll place the chassis, but as soon as i attempt to place an engine, driver seat, etc., the part collides with the chassis and flips it or nudges it off the grid. i can use /unstuck 3 command about 5 times out of 10 to realign the chassis to grid, but it doesn't help. I'll attempt to place again and if i do get it on the chassis without flipping it, the grid...
