What Went Wrong?

So I was fooling around with some modding(first time playing the game since I go the expansion) and when I edited the two expansion classes, the mastery “plus” button is missing it’s graphic as well as it’s description text. I honestly don’t understand it, the original classes all work fine.

How do I fix this?

You tinkered too much. Looks like you deleted the texture file for the mastery button, not sure about the tag though, looks right but… Make sure your classtraining file has the right tag. If it still doesn’t work, just delete that classtraining file and start over. If it happens again then there must be some kind of bug I suppose, I haven’t tried editing the new classes
