its been behaving oddly since the update:
-shooting at enemies only to die and see my bullet counter go back up, as if I hadnt shot them at all (although I have the sounds and animations going on)
-not able to shake heat seekers with flares or ecm jammer, no matter when I deploy them
-getting hit by heat seekers with no lock-on warning
-being critically damaged or sometimes destroyed in the tank with only 1 shot from another tank or rpg, from the front (!), also reactive armour not working occasionally
-c4 not detonating despite the remote beeping in the soldiers hand (usually happens when you switch from c4 remote back to main weapon)
-dying despite having gone behind cover for 2 seconds (apparently bullets can bend around corners)
plus more besides, but most of these do seem lag related, even though my game doesn't usually show the tell tale signs of lag
