And in this directory are also worldname.fwl.old and worldname.db.old. These files keep the state of your game before the start of new sesion. It means when something goes wrong, you can logout, remove the ".old" suffix from both files and start the game again and you have the game state before the last sesion starts

If it kept more than just one level of these they might even be useful. Most people don't have the learned reaction of not running a bugged game again until all saves and backups are secured, they go straight back in and overwrite the one good .old file.

The simple answer is super wrong. "Send them your save file" is pretty basic stuff.
