Hello from PAXEast! @CollinPotato and I are in the hotel lobby working on updating all servers to full 1.7.8. Doing so requires migrating all player files to the new UUID system which can take quite some time and only happens the *first* time a server starts up on 1.7.8. Please be patient with us as we migrate one server at a time. If a server is down, it's probably being migrated. If a server is up then it either is on a protocol hack to allow 1.7.8 players to connect or it is actually updated. If you are getting a message like "Server sent invalid data" and getting disconnected, that is a known bug https://bugs.mojang.com/browse/MC-52817 Lobby2 was the first server updated so if you are directed there, don't worry, that's normal! Once again, please be patient as we work to update everything, it's not as easy and fun as it sounds. Thanks for playing Minetime ;D
Sounds like you're making good progress! I hope to see the server up and running soon, with your developing skills, it shouldn't take too long
I don't think they've made a version of Huzuni for 1.7.3 and above, so I'm gonna keep playing on 1.7.2 till Huzuni gets updated :3
