There is a 100% certain way of reconnecting to Insomnia events, even if you disconnect 50 times.
1. Install wondible's Connect Buttons mod
2. Go to Settings > Server and enter the following values: Server IP: 74.91.124.81, Port: 20545
3. Click the "Connect" option in the game's main menu whenever you disconnect
Any clan leaders who don't have the server's IP address and port number, ask me for them (we changed them a few weeks back, so if you have the old values ask me for the new ones).
