I lost a precious course in Rise!
I've been developing a curriculum using Rise for the past several months. I've written 21 brief courses, but can only account for 20 of them. As I develop new courses, my practice is to duplicate an existing course, change the title, delete the old content and create the new content. The easy/logical answer is to say I accidentally overwrote the missing course, but I am VERY careful when I do this so that doesn't seem possible.
Any other ideas on how this could have happened, or if there's any where I can search for the missing course (note: I've gone through the deleted files already)?
I just don't want to repeat this error.
