Decided to make a new thread. I'm backing up the minecraft_server.jar and the current world (in addition to the backups I already have). I don't know how this is all going to work, so expect the server to be up and down while we figure it out. we rely on hey0's mod pretty heavily, so at this stage we really need to have that updated before we can all get in again. I can get the old server to load, but the client doesn't connect. I can get the new server to work with the new client, but no hey0's mod. So I might make a new world with new server/client and we can much around for today. Any objections? Then we can decide what to do with the old world once hey0's mod comes out. Bottom line is, I don't want people playing on the old world without hey0s mod at this stage.
