Selecting python deletes the project

We had started the intro tutorial and had added a heap of code. We changed the language to javascript and then to python just to look at it. We saw the JS code, but then we never saw any python code and the project was gone.

That’s a bug. And how can we get our project back?

Update: we found a backup - saved in the pngs (which we thought was very weird, but interesting!). So we are OK now, but that still leaves an issue with the python viewer.

I should add, that we didn’t see the save files until the next day.
