Hello folx,
I recently started working on a procedural muscle plugin together with a co-worker. Sadly I lack in python knowledge, but together we were able to cobble something together, that somewhat worked.

However, since recently, the plugin's UI, the tab that should contain all the settings, no longer appears. I double checked my folder structure, rebuild it - nothing. We didn't even change anything in the .res or .h, I'm lost and close to loosing my mind, since I can't find why the heck the UI does not show up anymore. They don't know what could've caused it either and sorta gave up on it. "Must be some cinema4d fuckery"

This is my current folder structure - has anything similiar ever happened to one of you or do you know, what might've caused this?

Ty
