I've got a problem with my actors. When they are not for more than 50% on a wall, it falls through that wall. Also, when my actons stand on eachother, they do the same. This is my game.

When you try to place red on blue, it works perfectly fine. But when blue is on red, red falls into the ground, and sometimes red disappears...
Does someone knows how to fix This?
