How to Fix
This guide is dedicated to who is trying to play Youngblood on coop and is getting a horrible lag, desync or random disconnections on the game with the error "Connection Lost".
It's simple, the two players have to:
- Download and install Hamachi from here.
- Launch Hamachi.
- Create an account.
- Create or join to a group where you coop partner have to stay too.
- Once your partner and you are in the same group and appear with a green circle launch the game and play without problem.
Doing this, my partner and me fixed all kind of connection problems in this game, I hope it works for you too.
