Actors falling thru xInfinite actors while off screen

[Novice]

Why does this happen? I have a player that has y=y+5 on draw actor it has key down events for left and right, i have a ground actor that is xInfinite and collision between them, the view can be moved left and right. Whenever the actor moves while off screen it falls thru the ground. I tried this with non infinite actors and there are no problems.

It's a bug. I will fix in next version.
