The plugin has been fixed and you can now use "/payrank purchase" command again!
The problem was caused by the use of obsolete and deprecated APIs. The plugin was refactored to use the new APIs and HC's UUID cache service.
There have been issues reported concerning ranking up with in-game money on Eco. Players have reported not getting ranks that they paid for among other promotion issues. We are going to be fixing this very soon as well as other bugs & glitches. For the time being do not use the /payrank command!
If you are currently having this issue or have other bugs to report please leave a comment below with your MC username and the issue you are having or have noticed.

Do not use the /payrank command!
