Daruma automatically saves backups of your CustomNPC player data.
If you lost all your quests and NPCs talk to you like you've never spoken before, your player data was somehow deleted. Follow these steps to recover it (Note, this is not guaranteed to work correctly, many errors can possibly occur within the map if you do this, this is a last resort.)



Exit the world/Shut down your server before doing this

The backup json files are organized by the time they were created, the format is: (Playername[Year-Month-Date] {Hour Minute}) UUID.json 

Find your player name, and rename the file. Delete everything in parenthese, and keep only the UUID.json, i.e: abc1d-ef23g-45hij.json 

Copy that file, then naviagte to Daruma/customnpcs/playerdata and paste it. It should ask to replace a file, click yes. If it does not, you renamed the file incorrectly.

Your playerdata should be recovered! You can now load into your world/ load up the server again
