![empty pcb.png](//image.easyeda.com/pullimage/oEgRTcHafFd8hELupHarBA3IVUBuvOyEhsSQTXYS.png) I spent countless hours carefully placing components on my pcb. This project has an external interface requiring extremely precise placement of buttons, holes, etc. I was so careful to save after every minute alteration. I exited EasyEDA to take a well deserved break, and when I opened it back up, nothing was left but an outline of my board and a lonely diode. The diagram above the blank outline is an earlier attempt that I'd abandoned in favor of a new, fresh approach; but even that has many missing components. What is the point of saving your work, if it gets ruined anyway. I'll never get those hours back.
