Collisions aren't accurate to object

[TimPM]

This is my first attempt at using Clickteam Fusion 2.5 outside of the tutorial (even though it's basically an all boxed up reskin) and there is occasionally a gap between the box and the ground depending on what side it falls on (mfa:Jake's Box Simulator.mfa). It's not exactly game breaking but it's very annoying.

Also on this game here (mfa:Falling person.mfa) which uses a more complicated model, it falls through the terrain at places.

If anyone could shed some light on what I'm doing wrong that would be greatly appreciated.

physics objects must have the hot spot set in the middle. having said that, this is nothing you can control, because the BOX shape that is applied will do this.
i played with the jakes example, and showed you a way of getting around this:

changed the collision shape to first object; and in the animations made it loop past this, with the original sized active.
