I have a strange problem when scrolling through the height levels of the tactical screen. The cursor does not stay on the same coordinates when going higher or deeper, instead it jumps to non-random fields for each level (to the left, to the front, etc), messing up a possible blaster-bomb flight path and causing other problems, like strange pathfinding. I also tried this on another computer with another mouse and it is the same there. It really makes me wonder why nobody posted about this before, it is a rather obvious problem.
Not sure if this is a bug or strange feature that I don't understand.
Personally i think it is a rounding error, a programming mistake. Maybe someone forgot an INT(height) or something?
