Whoops. Used wrong permission when copying over latest changes from MonkeyBrains plugin. It's now fixed and back to chests.silk.
For those who don't know what MonkeyBrains is, it's my own plugin that has everything and the kitchen sink in it that I use on my own servers. It was updated with the latest changes for 1.14 but when I ported the changes over to update SilkChests, well, I guess I forgot to change the permissions...
