What is your intent? If the blur between the base obj and the instances is the issue you may want to try making real instances in the replicator. It is more memory intensive, but this may not be a bug since w/o them being real instances they are sorta cloned and bound to the original object this allows lot less memory. Also depending on how you are moving them...I am not sure what you are trying to do exactly from your description.

No need to think outside the box....
    Just make it invisible.
