I created my own private course for Japanese vocabulary that I spotted in the wild.
Just now I had a very “intense” moment while creating new items. Somehow I added all the words to the database instead of my single level. So far so good. But then, I couldn’t find a any way/button to append those new items to said level without creating a whole new level. So I made a semi-working workaround by creating levels directly from that database and delete the ones that already have the items from my first and single level. After that, the database was gone. Nowhere to be found anymore. Also I didn’t find any “recover deleted level” function - in case I accidentally would have deleted the wrong level.
This experience made me heavily cautious of editing course within Memrise. From now on I’ll only work with prior made text files and the bulk add function. Or IS there a way to handle this easily and without having to fear data loss or having to retype everything if I misclicked?
