Page Refreshed Automatically and Most of My Mind Map Is Gone

[2032899884]

When I was working on my mind map just now, the page suddenly refreshed by itself and went back to the initial screen. Then I clicked “Open existing drawing,” but all the maps I had made were reduced to only about 5%. What should I do? I tried closing and reopening it, but it still doesn’t work. Does this mean there’s no way to recover my work?

What version of drawio are you running? What browser and version? Where were you saving the diagram to?

I don't know which version it is — I just open it directly in the drawio.com. The browser I’m using is Microsoft Edge. I saved the diagram to my computer under drive D:\Users\Documents. I tried to restore the file to a previous version, but there were no previous versions available.

Just wondering if it’s still possible to recover my mind map?
