Issue:
Patch 7 Introduces progression merging to improve compatibility, however it does not function as planned due to Multiclass nodes.
Possible Workaround:
Include all base game class progressions with additional multiclass nodes, providing a solid base for us to work from?
There appears to be an issue with progression merges that are not at level 1 and multiclassing.
A theory is that the when a progression merge occurs, it will create a separate "Multiclass" node, leading to some features not being included.
