After a server restart to install unrelated plugin (a listener that changes how TNT explosions are handled), PS threw up the following errors on startup:

Errors continued after TNT plugin was removed, and PS .jar file was replaced with fresh download.

Deleted ../PreciousStones folder and restarted. Issue went away until config file restored from backup and plugin reloaded.

Update: upon troubleshooting the error seems to be caused by these two field configurations.
