After I update your latest runtime,a problem has been bothering me.
For example.
In the default state,imageA is Invisible.
I only make it visible in some animation.
But once I switched skin, the imageA will become the default state.
I run your example in unity.there is also this problem.
I often need to use the spine animation like this.
