Are any of the player files in plugins/BeaconWaypoints/players empty? There might be an issue when it's writing player data to the files, possibly because of there not being enough storage space to save to. Also, could you check if there are any errors when it's trying to save? That would be when the server shuts down, the plugin is reloaded, or every 5 minutes when it autosaves.

I still have alot of storage space, there don't seem to be any issues with saving i think cause there were no messages that indicated anything wrong however it didn't mention saving either so idk.
