We have a cheater on the server - player363027 joined my tail gunner and shot off my tail and I died losing over 7,000 score. I thought it was an audio bug. Below you can see his name and I've included stat page https://il2-fl.ru/en/stats/sortie/103438/0?gamerId=531&tab=flight-log

This player is banned for 1440 minutes. But, you close the shooters so that such situations do not happen.

I thought he was a new player and was trying to communicate to help him out.

FYI, there's a known bug where random people can jump into gunner seats, locked or not. I've had it happen multiple times on multiple servers. I brought it up to 1C about a year ago and was told "they'd look into it" but apparently its still happening.
