I am using mecabricks to create Minifigures and other elements for a projects and have created around 25 different builds that were all in my library. There has been no issues at all, however I was just creating a Minifigure and when I tried to save it, a loading bar appeared, followed by an error message, and now my entire library is empty, and all of my builds are gone. Furthermore, I have just tried recreating a Minifigure and saving it and although it says it uploads, my library is still empty with nothing saved. Can anyone help, I was creating these builds for a university project, for which my final deadline of my degree is in 1 week! any help would be amazing, thanks.
