Ok, here's a screenshot.
I used the "Army Zones" distribution, so it's really easy to see.
https://imgur.com/gallery/5oXOVNmI actually really LIKE this feature (it enables some game modes I'd like to use), but I'm confused by why it's happening and whether it's something I can arrange to have happen reliably. (Toggle on and off, ideally, I suppose, since lots of other people like using limited full distribution or other play modes which wouldn't work with this kind of distribution.)
So, what's happening? Is it possible to take advantage of it consistently?
(It seems quite consistent on this map; I've played a lot of games on it and have never seen a wasteland in a distribution territory.)
