Nevermind, uninstalling and reinstalling did the trick. I was a little reluctant but it looks like my savefiles are ok! I will post a reply if I find an error or something.
Error message related to cookie-blocking, which Twine uses to handle savefiles.This most commonly happened to me when trying to run the game on a Incognito/Private tab
updated from 0.61k to 0.61l with the itch.io desktop client, now I can't play. Window is just a white screen. Help? 馃槶
