Was in a 3v3 battle on center of gravity, allied units sometimes turned red for no apparent reason (sometimes all in an area, some times a random few).
Sometimes enemy units will turn blue/green also, without giving away what unit they are unless they're revealed by recon, etc.
When you zoom in on the bugged units, it will turn to it's normal color, and will remain that way until you move you cant see them on screen. Bug seems to affect random units and blobs)
A variation of the same bug happened to me during the campaign - in fact you were able to see the unit "selection circles" through them. Like a thin line of missing pixels making the bright green selection visible right under the tank turret f.e.
Also noticed weird texture problems sometimes, black water for example, after tweaking the shadows option water appears normally though I still get the impression that something is wrong when quickly zooming to a city etc...
Any ideas on correct graphics options or something?
