It is impossible to attack

[Pashkinz]

our alliance is facing a problem. our players cannot attack one of the opponents. when we start fighting him, the game crashes.
I asked the leader of the enemy alliance what the problem was. he said that this player has not been online for a long time, so he has an old version of the game, so our attacks are not possible.

can you fix this bug? it turns out that the leaders of the alliances can use this on purpose to win
