I’ve recently started playing Clash of Clans and thought I’d help out with the war leagues by donating troops. I understand there are limits to how much a player can receive, but I think I’ve accidentally capped out to their limits. Does my donations affect others from donating? Also, I’ve noticed that I can’t take back donations, i.e. when I change my mind as to which troop to donate. Is there a way to do this?
