I was flying my P-63A-5 when I was teamkilled by a friendly P-38, who unfortunately ran into me, which the game counted it as me killing him. I was greeted by a -31K SL penalty because of this.
you can report him on the replay server if you want:
(log with your GJ identifiants).
But more important, you have a nice bug who credit you of the kill on the P-38 even if you are just ram by the P-38… Normally it should have counted a crash for the P-38
Maybe go doing a bug report here:
