Hey, boddy! Minesweeper server kick me in 2-5 minutes, and 2 seconds, when i'm reconnect. fix it for your valhalla place %)

Minesweeper mode is still in early development and it's already a miracle it works at all since it goes against the very nature of OpenTTD multiplayer design. I shut the server down until it's fixed which likely won't be any soon as right now I don't even see any technical possibility to fix all the issues so it would require some changes in OpenTTD itself to make it work.
