Kicking client will cause to an complete client crash ( Tested it only alone, cant say if it crash a victim if you dropclient cmd on him)
Caused by user error. If you want to run a command on the server, you need to put rcon in front of the command.
After Changing Map you can't leave the game.
We have a fix ready for this, it will be included in the next update.
Ping after changing map isn't displayed correctly ( maybe cause rcon logic thinks we the hosts)
You ran the map command locally. Meaning you are no longer connected to rcon but instead you are placed in a private match. This is also why the leave game button does not work.
Locked the thread. Learn to use rcon.
