I have a couple of asks for you that will help me greatly.
First, could you provide the crash logs that you are receiving on this.
Second, if you could provide some screenshots of your Blueprints so I can see exactly how you are setting them up that would help a lot. If you have a small sample project that is experiencing the crash you can send that as well.
Lastly, the link that you posted at the bottom of the page does not actually lead anywhere, I am receiving a 404 error when following it.
