Multiplayer Problem

[Cosinus]

Whenever i play with a Friend against 3-4 AI the Computer doesnt synchronise our Moves.
That means:
-I start to invade an Enemy, i destroy him and still he is Alive and wide-spread on the Map of my Friend.
-Whenever we share Technology we dont get what the other gave
etc, etc...

Anyone else noticed this Problem and/or have a Solution for that?
