Probably not an accurate topic title. For several years now, I have designed a number of boards and been able to update from the schematic without problems. This time I wanted to keep the original as well as using it as the basis of a significant upgrade. So I created a new project, and moved copies of the original directory into it. So far, ok. Created new symbols and made revisions to the schematics. Moved to Pcbnew to create footprints. Saved the first one to my project specific library and discovered that, while my library made it to the new directory, its contents did not. Easy enough to fix after I finished the new footprints. Combining my two libraries with the same name was easy. But something is wrong. When I attempt to upgrade from schematic, it wants to replace all the components with new ones. To add to the confusion, it can’t find two footprints. I found them in a rescue lib. How do I get it to look there? Just what are rescue libraries?
