I played a game today where this bug happened. When watching the demo, it appears stealth fighters (but not other aircraft) get locked into a loop that causes them to climb higher and higher. They'll do the same thing in the horizontal direction, going off screen quite a ways, but they can be ordered back onto the map from there. In the vertical direction giving them orders appears to have no effect, they just keep doing the same maneuver over and over again.NOiZE wrote:being able to reproduce it will make it easier to fix that bug...
What exactly starts this process was unclear to me, but to replicate the bug it is probably sufficient to build a bunch of hawks, set them on a patrol route in an area with some terrain relief and let them fly around for a while. One might induce the bug faster by attacking the patrolling planes with some other stealth fighters, causing them to do more maneuvers. Whatever event causes this exactly seems to have a relatively low probability of occurring, but once it occurs the plane continues climbing indefinitely. The bug seems to happen in most games that have a lot of stealth fighters flying around for a long time.
