Deleted the content of training cell by mistake

I deleted the content of training cell (in the left) by mistake and its garbage now. Undo or reloading the page doesnt get the connect of the cell back. I can look at the solution to get the file content which I dont want to. Is there a way I can get back the content of the cell?

To be precise, I deleted the content of Launch File {1.8}: generate_dataset_96.launch by mistake from the left panel.


Close the academy and go back in. That should fix the problem :slight_smile:

Working on preventing this error from happening again. We’ll keep you informed

cool, thanks for the help.

Thank you. I could see it.
