I find this odd.
Player teamkilled 3 times, yet they dont show in server replays
They might have some privacy settings enabled that hides their real nickname and/or clan tag and gives then a randomly generated one while they are in a match. In the server replays their real nickname and player ID is shown. Best option is to watch the Server Replay to the point where the teamkill occurred to see who it was who did it.
If the match is not appearing in the list of played matches then it might not have finished yet if you left early, there might also have been some sort of bug. I don’t think Custom Games are saved as server replays either.
not sure where my reply went.
I waited over an hour, server replay did not exist.
Do you still have the client replay?
Edit:
You can find them by clicking “community” → “replays” top left in hangar, there should be a session ID shown for it that you can search on the War Thunder website to get the server replay
just move on. ucnt fix the world XD. trust me.
