Hey sorry for late reply, I was on the road, over past few days and wasn’t able to create project which would reproduce the issue. But here is download link:

Just open this project, and check character component. You should be able to select one class for the Attributes field.
In that class there will be property Health (under resources category), And as you can see you can’t change properties inside Health struct.
I checked it against latest binary.
