Hey lennaert, thanks again for the response.
You can have copies running different animations though. That doesn't explain why it doesn't work. Unless it is by design that when the default animation speed is set to 0 then all of the animations within are set to 0 automatically, which doesn't really make sense to me.
I have updated the example to show another instance running another animation at a different speed. It still works, all as long as the default animation is set to at least 1.
