Something made my language file stop working when it automatically updated to 2.0-RC2-SNAPSHOT-T20190626214956-b90 (https://pastebin.com/bAQRpR08) I restarted the server, it showed this: https://pastebin.com/x6Qx40zG

I also checked and compared a new generated en.yml to my custom lang, nothing where gone or changed.

Could you please share your language file with me

The confirmation messages didn't contain a valid string for some reason.
This should fix is: https://pastebin.com/ECT8u5D2

Thank you!
