Collisions between sprites (as well as groups) and tilemaps won't call the collision callback in 1.1.2. This is already reported as an issue in git. As far as I can see the problem is that the sprites stops moving, thus body.deltaX & body.deltaY become 0, before there is an actual collision. I'm now looking for some sort of fix or workaround for this, so I can use 1.1.2 in my project.
