There will be a patch during the week of Monday 19th of September (no date has been set yet) that will help address some of the issues that some server owners have been having with Corrupted Saves. The change is going to involve altering the way that saves are recorded, so these will be incompatible with previous saves.
To prevent the possibility of having an issue with the patch that causes you to irrevocably lose your save, PLEASE CREATE A BACKUP OF YOUR SERVER'S SAVE FILE.
Information on how to back up your file can be found here.
