Hey. So recently I went to try a plugin with my friend, called "ProjectKorraCore". I simply installed the newest version of the plugin and the corresponding version of Spigot for it and it did not work, and did not appear under /plugins. Since it also works with Bukkit, I tried that as well to no avail. I looked at my server log for clues and so I'm not sure if this is helpful but this is what it read (I actually had to delete a lot of the lines because they just were repeats because of the 10,000 limit.)poiler][/spoiler][03:34:33] [Server thread/INFO]: Starting minecraft server version 1.8.3
