Custom Soldier Class in XCOM 2 not Working when viewing abilities

So I just got into modding XCOM 2 and ran into a problem and I could not find any solution in the net. The problem appears when you view a custom class soldier's abilities. What will happen is that it will do nothing and the game will hang.

The solution is quite simple:

XComClassData.ini in Modbuddy

Make sure that "bHasClassMovie" is set to false. Save and build your mod and the problem will be gone.
