The realm has, on multiple occasions began performing more slowly than usual, followed by timing out for several minutes. Later upon reconnecting to the realm, more than an hour of progress has been lost. No special actions or method has caused this and as such cannot be replicated, however the issue has only occurred later at night (11:10pm- 12:50am AEST) which may be somewhat related. (UPDATE: The error occurred again at 3:00pm) The first time this bug occurred, I contacted the realm's owner so that I could view the configuration and noticed that the backups which should have occurred when the server lost progress did not occur, and the progress on the realm was at the point of the previous-latest backup, leading me to suspect that a failed backup may be the cause or related to the issue.
