Having this error when I log in using 1.7 - http://pastebin.com/3eX9Lupb I'm using this (http://build.true-games.org/job/ProtocolSupport/388/) build of ProtocolSupport on Paper Spigot. Output of /ver: This server is running CraftBukkit version git-PaperSpigot-"4c7641d" (MC: 1.8.8) (Implementing API version 1.8.8-R0.1-SNAPSHOT) Attempted to use this thanks to ViaVersion adding a way for both to work together - Error occurs both with & without ViaVersion. Does anyone know what the problem could be, or if there is a bug without this issue? I did attempt to contact the author through the resource thread, however I have gotten no response. Thanks to anyone that can help me out.
