So, I came back this morning to check on my afk account (HorribleNerd), but the pc it was running on lost connection. When I tried to join again, I got this message (tested on multiple computers, same result):
When I logged in on my main account, it showed that my afk account was still on the server. Dynmap says the same.
Any ideas on how to fix this? (Maybe kicking the player from the server will help? I dunno.)
