I'm running a modified Direwolf20 2.6.0 (Minecraft 1.12) and I could not get the morph editing to work. I ran it through the validator and everything but it wouldn't work on the server. The bigger problem was that the commands suddenly stopped working for reloading the blacklist and morphs. It just doesn't do anything anymore. We've tried re-installing the mods etc, but still isn't working.

I don't really know how to even help here. It sounds like some kind of episode from Goosebumps 😂

I'm not a magician, send the morphs.json file, or whatever you've been editing.
