Hey! Unfortunately we cannot roleback servers. Next time I suggest you use an antigrief plugin such as world guard and backup your world regularly. That looks sick and I hope you pass!
Hey! If you install the plugin Essentials you can use commands such as /sun to toggle the weather. You'll need OP (which can be found below), I've also added a tutorial on how to install plugins.
your indent is wrong, it would be:
on join:
set slot 0 of player to chest named "&8» &bLobby &8«"
on rightclick with chest:
if name of tool of player is "&8» &bLobby &8«":
wait 1 tick
execute player command "/lucky list"
Hey! If there is no player activity on the server (you will need to join it to keep it up) the server will self hibernate. This is to make room for new servers starting up. If this is not the case, please could you copy your logs from your latest.log file in the form of a https://pastebin.com/ and put it here as a reply Thank you.
