I seen number of people report this bug in past, I never had it happen until today...

Here is a picture of how it looks like... its actually picture of my buddy getting the same graphical glitch:

Basically all units dissapear, u can see map contours, grass and if there is water u can see the bottom but no water.... you can see explosion effects and smoke, but you cant see any units, I tired changing every option in game while playing online and could not fix this, although my friend had this glitch go away on its own once. The bug occured for me when I was investigating a puma wreck. This is quite terrible graphical bug, when exited online session and started another everything was fine then... but when this occures you are forced to basically quit the game.
