I have a problem with a ListIteratingSystem I added. Ash is trying to call it's update node function, but failing because the node list is empty. At start, their are no instances of components that are used by the nodes that this system is using.
I'm not having a problem with other ListIteratingSystems in my project, so I'm wondering if I'm misunderstanding something about how Ash works.
In the meantime, I've converted it to a regular System and that's working fine.
