When duplicating multi-state object more than once project no longer visible in preview
I have a multistate object with 10 states. I want to duplicate that object 5 times.
When I duplicate it once (i.e. there are two instances of it) the project continues to preview just fine. When I duplicate again so that there are three instances, when I try to preview the project it's just white - there's nothing there.
If I delete the third instance (so that two instances remain) it previews fine. I can swop the different instances in and out of the project - as long there are no more than two (desn't matter which two) it previews fine.
Does anyone have any idea what I might be doing wrong?
