Hello, I have been trying this plugin on 1.14.4 and for some reason, I cannot get the plugin to work in PaperMC 1.14.4 242, the plugin doesn't show up in /pl, and using commands result in nothing happening.
The Herobrine 2.x.x release series started with the release of Spigot 1.15.1 and therefore does not support 1.14.4. Additionally, there are no plans to make it backwards compatible. I apologize for the inconvenience.
