Ok, it works, but with many limitations.
1st issue - you can't add container to a family, what means if I have multiple sprite objects in the family which should share the same functionality (e.g. an array) i have to create a separate array object for each individual sprite object, because it's not possible with the family.
2nd issue one and the same object type can't be shared by different containers, which is very limiting
Actually it would be nice, if more modularity features would be added to C2, like proper working container with hierarchies and object blue-prints (groups of behaviors and object types).
