I have also seen some flaky things going on ...
Last night while flying, I ripped the wings off of at least 5 planes, watched them go into the ground and never saw the "kill" message and didn't get credit/perks for the kills.
During one flight, the first plane I shot down, I received the "kill" message, I then proceeded to shoot down two more planes and never received the kill message on those 2 planes.
Also, over the weekend when the knights won the war, I never received the 20 perk points (I was logged on), rather I had 20 perk points deducted (net -40 perk points).
