TG Battlelog Enhancements & Game Launcher. Simply load this plugin and go to http://tacticalg.com/server1/Battlefield 4 Server Seeding plugin by Tactical Gaming.
All this plugin does is click "Join Game" if you get disconnected, so you can keep seeding a game server unattended.
To activate go to a server page like: http://tacticalg.com/server1 and join the game. Leave the tab open and if you get disconnected the game will relaunch in 30 seconds.
If there is an error it will attempt to relaunch the game. Supported errors:
"Game disconnected: Client closed down connection. Check your network connection and make sure that port 3659 (UDP) is open."
"Game disconnected: your connection to the server timed out."
"Connection to the server has been lost. Please check your internet connection or try again later."
