how does work floating points, i have a part that is boken since i moved it ...
it has a lot to do with rounding numbers and how precise numbers can be on computers.
the further the part is away from the map origin (top left at 0, 0), the more numbers get rounded and the more precision is lost.
the precision does not go down linearly with increased distance, but precision is lost whenever you cross another power of 2. this means that for example after x: 128, a bit of precision is lost for the x coordinate, then again at 256 and 512 etc. the precision is separate for x and y.
if you move a part into another level of precision, it might change the physics in some ways.
If the part stays in the area where it has the same precision for x and y, I can't think off the top of my head why there could be a difference
