Plugin Version: 7.2.2 Spigot username: Sil3ntassassin7 Issue: When I put the plugin newest version on my server it says that my worlds are using a older version and to downgrade so I downgrade to what version my worlds were generated on and it say loading EpicWorldGenerator and then it will say "Stopping server..." and it won't create a crash log or anything.
