I have the html-version. How do I load a saved game? When I close the browser and open it again, the slots are always empty.
That‘s a browser issue. You need to check your privacy settings. Also, which Browser are you using? And which version? We know that Edge for example has massive issues
I tried it with chrome, safari and firefox 77.0.1 64 bit. Unfortunately still not possible :-(
Is it a cookie-issue? I had the same problems with rabenstein, but that was a short game so it didn't matter.
