units get invisible (Graphic bug?)

[Inspexor]

So i have another problem where things get invisible..

I just played a Survival on 5th Dimension with 3 other players and for some reason suddenly every unit got invisible.
You could see the units barely but you could select them and build with them etc

Every player in my lobby had the same problem.
The enemy units couldn't attack us but we could attack them.

Is this some upgrade on the Cybran-Com (would be pretty damn OP tho..) ? Because there were no buildings that could turn our units invisible or something like that.
The shield-generators of the enemies were also invisible.

Just guessing but units like stealth generators really screw up the game.

I think sera commander gets a cloaking field

No, that's a repair field..? Or are we talking crazy mods?

in Black Ops which i just assumed the game was using for some reason. Now looking at the game log blackops was in the game.
