(I'm making the assumption that this report regards the movement noises that continue after the unit stops moving, and can't be stopped other than by reloading the game.)
Will not fix? Unacceptable! This problem has been there before, been reported (including by me), been fixed, and then returned an update or two later, then reported again, fixed again, etc.. It obviously can be fixed, and, once fixed, should be possible to keep fixed. Whatever you're trying to achieve, that keeps causing this problem, quit trying to do it. Trust me: The absence of whatever it is isn't bothering me a bit, and certainly won't make me quit the game. If you think others will quit over the absence, then it should be important enough to put some real effort in, and get it done properly. This is immensely annoying, and more so because it keeps happening. It's destroying all enjoyment of battles.
There's no surer way of making me walk away, than to keep annoying me. So far, I've been patient, waiting for the next fix, but, if I loose faith that a fix is forthcoming, my patience will snap.
