There was a server crash today (or yesterday) due to a terminal duplicating itself for a few hours that somehow caused all of the configurations to reset for a brief moment causing all kinds of chaos which most of was quickly fixed by using a backup, except for one, factions. The symptom that was caused by this was that everybody who had been inactive for a certain amount of days was removed from their faction (except for the faction leaders I think). This was caused by a rather stupid decision made by the creators of "Factions" that placed all of the configurations and player files outside of the normal folder which made it excluded from the normally scheduled backups, so I didn't have any backups I could use.

This problem should not come up again as I've include the folder in the automated scheduled backups. If you have been affected you can try to join your faction again or ask the faction leader, officers or even a server Admin to re-invite you to your faction. As far as I know the claimed areas of land has not been unclaimed by this incident.
