I start up my minehut server and then when it turns online, me and my friends can't join it then in the logs it says "DO NOT REPORT THIS PAPER THIS IS A BUG OR CRASH". It says that in the logs a few more times and the server stops itself. Is there a way I can use a previous save file because maybe some command blocks made the lag. Please help.
