smoke projectiles do not create a smoke screen for some time now - when the projectile is fired, its effect is a small cloud of smoke, the same as after the explosion of other projectiles, there is no smoke effect (smoke screen)
same for me, smoke shells dosent work. the smoke grenades work just fine but not shells.
I have add my observation here as well. Smoke shells are vanishing and then clouds of smoke are appearing in the sky or on the side of mountains. This ‘skipping’ occurs even when I fire down slope in near perpendicular objects such as buildings, rocks or the ground.
Are the bug folks working on this?
