Recently I made a new server and When I tried to boot it up, it sent me to the server before it said it was online. Then when I tired to op myself the commands weren't working either. Suddenly as I was trying things to make it work, it went into hibernation. BUT, the server didn't shut down. I was still playing on it and could leave and join it still too. I'm not even sure what's wrong with it. could someone please help?
