I have some Tinkercad designs from 4 years ago. In my list of designs, anything 3 or less years old lets me open it and work on it. For my 4-year-old designs, hovering over the thumbnail gives me an option to "Copy and Tinker". When I click on that, I get a pop-up that says:
Please leave this page open.
You will be redirected to the editor when the conversion is complete.
Well, it's been open overnight and it just sits there with the animated progress bar not showing any progress. The design is simple, a basic flat-bottom boat hull made of a squashed sphere with a few cubes subtracted.
This conversion process seems broken. Is there any other way I can recover that design?
