Revenge not possible

My fellow devs of the game i would like to understand why i cant make revenge against 2 players i lost 37 cups for 2 enemys that dont have the update made it shouldnt happen because if there is one update to make they should not make attacks i mean they can attack me and i cant attack them???very disapointed very much, i want my cups back or attack them i prefer attack
