In order to use any of my plugins you will need to run both the GalacticLib and MassiveCore on your server. There will be updated GalacticLibs below, however when it comes to the MassiveCore, you can use a custom one if you already have one, or you can download one from the following link https://www.spigotmc.org/resources/1901/ which will give you the whole zip, and all you need from that is the MassiveCore.jar.(edited)
