In BMCM (Bloons Monkey City Mobile) for Android, when I send bloons to attack other players, the game chooses a random player as my target, asks me the kind of waves to send and then gives me a couple Bloonstones for the attack. I never get notified about how did the attack end, nor I ever get any loot.
Is that because the target player is inactive and never defends himself from the attack, hence it never happens? I've noticed I've never ever have received an attack, and on Contested Territory I'm almost the only one which does even try, as if no one is playing the game.
Has anyone ever launched a successful attack? Is MvM useless on Android? I send attack after attack getting no loot, but having to build new facilities and research new technologies from time to time in order to send the next attack. Is it a waste of money?
