Whenever i play gren on maps like glycen and escort where you constantly got enemies to fire at, my mortar quite often reloads twice. This usually happens if i hold down the fire button for a couple of shots, release it, and then start firing again. The most annoying bug atm (which everyone already knows about, but still) is the one getting you stuck in other players and the smoking buildings thing so focusing on those first is probably a good idea. Yeah.
whenever i play grenadier, riflemen suddenly horde my location and all tanks are not to be seen in miles and when they do i like to drop mines in front of them
