Describe the bug This bug occurs whenever the Spigot plugin is loaded alongside my own plugin.

To Reproduce Steps to reproduce the behavior:

  1. Compile your own world generation plugin for 1.14, manually installing the API jar from release 0.3 into maven
  2. Put that plugin in server plugins
  3. Compile the impl from the source code of release 0.3 and copy that jar into the server plugins
  4. Attempt to start the server

I had to compile the JAR myself because the JAR in the release didn't have a plugin.yaml and the impl in the source code did.

I believe I fixed it

For anyone planning on using the 1.14 release, you HAVE to compile it yourself. The release build is incomplete
