So, I should probably clarify. I was a bit of a noob and said “shade” when I didn’t actually shade the API into my own plugin. I added the plugin version of NPCLib as a dependency. I just shaded (actually this time) the API into my own plugin (I use Maven and I use IntelliJ) and now I’m getting another error:

EDIT: So it looks like I was adding in an extra step… I just had to compile the plugin during the package phase of Maven. Marked as resolved.
