Technical issues and problems with WoGa.

Hello. Can you help with this problem? My friend and I are playing version 3.58 over a local network. When we simply move around and attack the computer, everything works fine. But when we attack each other in a castle or something, the battle somehow plays out separately for each of us. For example, I make a move, and then it shows that it's his turn, but on his screen, it shows that it's my turn. And there's nothing we can do about it. We can only reload the game. This happens constantly, and not necessarily on the first turn.

To make it clearer, I'll explain it better. I might have worded it confusingly.
It's like this: on his screen, it shows that I'm making a move, and on my screen, it shows that he's making a move.
