At 3:00 am EST the server experienced difficulties while attempting to save the map causing it to become corrupt. Because of this, the server's save file deleted itself. We automatically capture backups, however, we are unable to perform live backups so snapshots can only be created during restarts which is every 5 days. Player BPs were not affected.
This was simply out of our control and I personally apologize for any grief this may cause. If you've purchased anything on our store during the month of April please reach out to us at https://www.rustez.com/help to have everything carried over.
I've sent Facepunch the report to hopefully get some insight into the issue and help prevent it from happening again going forward.
