Mainline
I confirm that
- [x] I have searched for an existing bug report for this issue.
- [x] I am using the latest available version of AMP.
- [x] my operating system is up-to-date.
Intended Action
im trying to see the number of active players on my server ( at glance) in AMP UI
Expected Behaviour
to see the correct number of active players on the server
Actual Behaviour
in this specific example,AMP shows only 7 active players online on the server instance, meanwhile an active battleye rcon connection reports 10 active players,and game server performance statistics output line shows also 10 active players so it seems AMP isnt registering player joins and or player leaves correctly attached instance logs

Reproduction
install arma reforger, configure it as you wish and also enable logstats startup parameter https://community.bistudio.com/wiki/Arma_Reforger:Startup_Parameters#logStats and launch server download battleye rcon app and monitor server ,on AMP and in the rcon app active player counts in AMP differts than what the game server reports in performance statistics output line in the console,and what the rcon app shows
For clarity, the issue is not with the template user join regex - has been verified with the logs
