Hi there is an GUI Bug.
The actionpoints coloring is working fine BUT only in quickbar slot 1.
If you have skills in quickbar 2 or more the actionpoints costs "red bubbles" references to quickbar slot 1.
Hope you understand it

Example:
You have skill A in quickbar-slot 1 and it costs 5 AP.
In quickbar-slot 2 you have Skill B and it costs 3 AP.
If you are using skill A in slot 1 its right:
******But if you using Skill B in slot 2 it looks like that:
****** instead of
******because the program uses slot 1 as reference and not 2.
