Okay, we need some serious rules on how and when zones are transfered.
As it is now, the rules say that you can give any zone to anyone else you want. The rules don't say when, but since everything else is done the same turn that you take your turn, it is slightly obviously done while taking your turn as well.
But the problem is, that if you transfer an extractor, you could conquer it the next turn and gain resources that way, assuming the one who receives it doesn't give it back. Even worse, two players could trick a third player if player 2 takes it's turn between player 1 and player 3, and player 1 gives an extractor to player 3. Then player 2 can conquer the extractor and gain resources from player 3.
How do we solve this?
