Any of the following might or might not be network related:
There is a glitch at times in setup mode just when the fog is on…units start going their own way refuse to follow orders might get teleported back to original position after being moved.
It seems when a player quits at times all his units disappear in a sort of a game crash.
Some sound fx have disappeared like the ingame tempochange
When in viewer mode sometimes if the game ends and you get thrown out you cannot start or enter a game, have to restart the whole game
thats it for no
