If versioning didn't work, depending on the scenario, we will copy the originals out x' amount to the side. Verify the copies are acting as intended. Delete the original. Move copies back x' amount and reconnect. (I believe a copy to clipboard and paste aligned to current view will work as well, but it's been awhile since I had to do it.) If the copies are acting the same way as before you reload config, not much to do besides redraw. I don't think I have tried using dynamo for insulation spec, so I can't say without trying.
