Yesterday I played the game with my brother in lan at home, but after 20min, there was a sign that say: Connection with server lost. First in my notebook, but after a few seconds in my brother's pc too and game over. We don't have internet connection at home I was hosting the game. It was the first time that i played 0ad. The lan worked correctly. My notebook is a core i5 with win7, and my brother pc is a pentium4 with windows 7. I don't know any other info that could help. Only one detail, I have installed hamachi a fews weeks ago, maybe the vpn of hamachi could be the cause of this bug?
