ok, so this is weird
i was clicking near the borders of Sidi Barrani in a 31p map when suddenly while clicking maybe like 10/15km away from the coast of the province, the game selected it.
my first thought was, ok, the witish edge in the sea, between the province and high seas, it's part of the province which would also be weird because it shouldn't but whatever
but, here is where the things goes really weird, i wanted to make a gif using gyazo to have proof that clicking in the witish edge selects the province so I did the gif, but the gif doesn't show what i see in-game as i clearly see that i'm clicking at a considerable distance from the province, so something's wrong, either i'm crazy or there's something that changed between the game and the gif
i tried it twice, first one doing it at a normal level on the withish edge, second one going as far as possible from the province but still in the witish area, check it out
