Hi @TugboatBen, sorry for the delay...
Can you please try to run the command with debug enabled (hold ctrl while clicking on the button)?
It might give you more information about the family that can't be saved (the script saves the families that don't have a path to a temporary folder in order to calculate its size).

Does this happen regardless of the model that you run the command in?
