I'm investigating exactly into the issue reported here, but found no replies.
Did you got some additional info or workaround/solution for this issue?
Thank you in Advance
I am guessing that there is a conflict of interest between Factory 1 and Factory 2.
I get why you need to do this, but from the computer perspective, the wires are getting crossed persea.
You might want to consider just making individual parts without using the ifactory files.
