I installed Auto Rank, my server is 1.12.2. Everything seemed to work fine, I configured the rank I needed and did /ar reload. /ar check worked completely fine but when I do /ar check I get an internal error.

Paths.yml: https://pastebin.com/4CRiHJs7

Its a fresh install only thing I changed was paths.yml

You'll need to update Autorank, PluginLibrary and Statz to the latest versions.
