Difficult time with new mastery

I’m using the tutorial mod make by the developers as a reference point. As a first attempt I was just trying to figure out what files need to be present to make it all work… however copying crates “testadin” class over doesn’t even seem to be working correctly (fml).

Here’s what I have: all UI elements related to the 7th class, and the UI of selection, as well as the skill information for the same. I have the tags.txt as well.

Here’s what’s going on so far: I can see the name of the class and select it, but once I’m inside it, there’s no way to undo class selection, all the skills are missing and mastery bar doesn’t work.

tl;dr I’m confused.

Check your class table for the mastery ui and your classmastertable
