Missing ships

Hy today i played a game in multiplayer. And halfway trough the game my opponent and i noticed that what we saw on our screen didn't match. While my opponent saw me attacking with one capital ship against a small fleet on my screen i send in a fleet while my opponent had none. 

Also on my screen the planet was not colonized and had no orbital structes while on my opponents screen this was the case. 

I do not c this in the known bug list so i thought i should report it, Does this happen to other players aswell ??
