    I found that if you take two empty object squares, and have the first at a 45 degree angle, with the second directly on top of it, the second won’t balance on the corner of the first.....but if you set the first’s angle to 44.999985 it will balance. Every time you come back to the angle setting it has been rounded to 45, but if you set it to 45 then, it stops balancing.

      I'm curious as to how you found this number.

        @Deeeds I’m gonna guess trial and error, based off which way the square falls over.

          @Deeeds, @Aidan-Oxley is right...trial and error. It was fun LOL!

            @iTap-Development Two exactly round balls, one on the ground, one above it, falling down on it, and then bouncing up.

            What's the offset required to ensure the ball falling down never bounces to the side, always going straight up and down?

              @Deeeds for me it's 0. Having the exact same x coordinate works, unless it falls off after a really long time. Is it different for you?

                @Jack8680 Yeah, I'm getting immediate movement to the side. The upper ball bounces off to the right, by the third fall it's off the below ball and away...... free... dom....

                  Weird!

                  I have no idea what would cause these kinds of bugs other than some weird rounding error in the bouncing or collision maths.

                    @Jack8680 I'm pretty sure it's that... when the centre of mass doesn't quite line up exactly with the centre of the shape.

                      @Deeeds 0 offset works for me too.

                        Did anyone have the same result with the squares?

                          @iTap-Development When I had either a square flat and the other at 45° (or your weird angle), the square always fell down. But I had the square falling onto the other (a wall object).

                            @Aidan-Oxley my 45 (or 44.999985) was a wall and the 0° fell onto it.
