Angled Hinges out of position and exploding or destroying subgrids when reloading game
I have found when making hinge joints that if you leave the game or copy paste the build with the hinge at an angle normally 90 degrees, the hinges will either explode or destroy the subgrid when pasting or reentering the game, the only safe way around this is to make sure all joints are at 0 degrees when exiting game or copying build. this is not ideal as some joints need to be at an angle.
Jump to 3.20 on this vid to see an example of the mechanism. https://www.youtube.com/watch?v=zxYI5wwuL7U if i leave the game with that inside the arm and reenter, the mechanism has attempted to unfold inside the arm, yet as you can see in the whole video the mechanism is sound within the arm during all the movements.
