I have been working on a PCB for several days, there are a lot of connections and I have been ripping and rerouting a lot. I save the project often to preserve what I have done so far. Yesterday I worked on the PCB for about 4 hours, saving as I when along, at the end of the day when I closed the PCB screen, I saw with horror a yellow waning sign at top of the schematics telling me that there are no longer connected. I don't know what I did, but I suspect that when ripping one of the traces I pressed the delete key and did not pay attention to the message telling me that I will lose the connection to the schematic.
Is there any way to save what I have done?
