(darkness) Model error

[swift plaza]

I don't know how, I don't know why, but when I want to combine a model from MythicMobs with an NPC from the Citizens plugin, I get this error, can you tell me how to solve it?

Hi I'm AutoThreadBot! Don't mind me, I'll just be adding the helper team to this thread so they can see it. A human will get to you soon.

Modelengine is responsible for that connection, better ask them

Best we can do is tell you to make sure you're using the latest version
