During a build my server randomly shutdown with no special disconnect message, this happened yesterday morning also and after leaving for a while I came back to find my Google Drive account had been signed out in the backups tab (backups were NOT missing, just had been signed out for some reason) I would attach my log/console here, however that gets wiped when the server shuts down.
Server IP: cornman.aternos.me
(side note: why tf was there a 12000 server queue at 10:00 AM on a monday?)
