Larry, same problem here. Question; what do you mean by “re-exported”? Re-render? Can you share a project without having rendered it first?
I have painstakingly removed the referenced frame only, re-share… if another error, removed that specific frame also, re-share.. etc, etc. It can take days!!.
Your solution sounds wonderful if only I can figure out if I can share an un-rendered project.
Thanks for your help.
