Render system isn't initialized correctly

[NachoIannizzotto]

I was working on my own model for CPM and when I import it into my server, my friends see me as a Steve with a error on top of my head, the error log on the editor drops this:

I'm still unsure what's wrong. This is the log as well. logs.json

Try removing apoli, and any mods that depend on it.

Dou you have any morph like mods installed? The game is trying to render the armorstand model when this error is happening.
