Building blocks or reloading makes physics act strangely when subgrids are pushing into each other
Reported
If you push two subgrids into each other with a piston (the force doesn't need to be large), everything will be fine until a block is built or the world is reloaded, at which point the grid will start vibrating and the piston head will separate from the piston by a small distance. Reversing the piston and then reversing it again fixes the problem until you cause it again.
I have attached a zipped world folder with the issue and a screenshot of before and after building some blocks.
I have the same bug
