Welcome aboard, Mike! It's about time! You've got it. It's not that hard, is it?
I think MrRoadrunner will notice a hard-coded variable visibility. He might not notice when his battalion HQ is sitting out in the open and taking artillery fire, but I'm fairly sure he'd notice when the visibility changed from turn to turn.
I guess I may have to start watching replays?
Unless you want to win, of course!
Most times, when the LOS gets further or closer, I think it is just my age and waning vision.
