I want to get mythic mobs on my aternos server (I have both it and model manager) but I can't upload them to the plugins folder. I tried deleting the plugins folder and uploading a new one with the plugins in it but it wouldn't work. When I tried to request it to be added to the plugins list it was rejected because "It's on an external website." How do I get it on my server?
Edit: Just found that Mythic Mobs is available but I still need a way to get Model Engine on.
