I had the same problem. Go to the navigation on the left on the second icon "Kata" and you will find a search field on the left top side of the new screen. Try to find with keywords of your lost kata.

hi friends im new on codewars. I want to know how to search for a particular kata. I was solving a kata and then my internet connection went off. When internet started again i lost the kata and a new kata appeared on my screen. I want to know how can i get that kata back.
This site is good but hard to navigate. I also want to know to can i upload a profile picture.
