Hey!
After fiddling around with the editor for a bit i found that if i override a skill in the stats (i.e. same ID) it works fine.
If i try adding a new skill with a new, unused ID, i can not get it to show up in the GM spell book at all.
I confirmed the whole thing by changing the ID back and forth between an used and an unused one several times.
The project loads GM, targets GM and is an addon.
I'm not sure if this is intentional behaviour or if I'm doing something wrong here!
I'd appreciate any help
