Curious game that I'd like to experience more of, but when I build my first base my ships go invisible (can't select the fighters, perhaps they're used up building the base, and built ships have no graphic representation but might be movable) and the enemy ship doesn't move any more.

Edit - I also lose the ability to move/drag around the map, and "Quit Match" doesn't do anything.
