Funnily enough, if you set two AI infantry to the same waypoint inside a building they occupy the same space.

The collision boxes behave like rigid, non elastic bodies. Instead they should be elastic and it would become possible to squeeze through gaps. This could be limited to players only, since cars are still rigid (at least with the current damage model).

Mass closing ancient tickets with no activity for > 12 months; assume fixed or too trivial.

If this issue is still relevant in current dev build, please re-post.
