Customize FlameCord!
If you encounter issues report them, if you are a developer I'll glad to see you contributing to the project by releasing fixes.
Just pickup Travertine's original file and extract classes from FlameCord's jar file and then do: "jar uf Travertine.jar net/" "jar uf Travertine.jar com/"
SPARK-Patch will be always up to date, it contains patched BungeeCord.class for being modified, TravertineSemiPatch.jar contains only edu.* annotations update, no BungeeCord.class patch!
