Yeah I just have to keep setting the connection to LAN every time we go to a new map. I've been too lazy to make up a nice config for myself so I have to keep resetting everything every time I come to the server. Such a paaaain
Make sure you do this:
1. Start u ET.
2. Set it to LAN.
3. Join the server.
4. Dont worry if it shows unselected. In game you can check your rate by doing players in console.
Should be fixed without config.
