Appears as though that this wonderful plugin has dropped support recently and I would really like to see it get updated for 1.14. I see someone has a github issue open #28 there for a 1.13.1 update but I figured I'd make a new one since it is a different minecraft version.
Error I get when attempting to launch the server with PowerNBT:
[21:39:52] [Server thread/ERROR]: Error occurred while enabling PowerNBT v0.8.9.2 (Is it up to date?)
