I just posted a bug to the tracker about families. Currently if your family already has just a sprite with the rts behavior, then you add another sprite with the rts, and bones behavior it will cause an error runtime.
My question is was this meant to be doable? I know its automatically a bug because of the crash, but Im getting other strange things to happen when i mix sprites with various behaviors.
The wiki says its used with objects of the same plugin type, but it says nothing about behaviors, or if it can be used with other families.
