Emergency workaround to save file if scadnano Save fails

If you experience this issue with a large design that you don't want to lose, here's a workaround to save the file by pulling it out of localStorage manually.

In Chrome, open Developer Tools by pressing Ctrl+Shift+I, or clicking on ⋮ in the top right and clicking on More tools → Developer Tools:

Click on the Application tab, then on Local Storage, then on the scadnano website, then on "scadnano:design":

Double-click on the text to the right of "scadnano:design", under the Value column, and make sure it is all selected. At that point you can copy and paste this text into a local text file ending in .sc.

I cannot reproduce the error. Right now the file saves okay even with enhanced protection enabled.

I do recall getting the error before. If we can reproduce it, we should paste a screenshot of what happens here.

I also can no longer reproduce the error even if I put safe mode back on in Chrome.
