Uxcel changed the challenge overnight

Hello, it seems to me that you changed a challenge overnight. I have screenshots of what it looked like yesterday. I submitted my work in, and learned this morning that I didn't pass. When I checked back on the challenge to reupload my submission after making some corrections, I found an entirely new page, asking for mobile AND desktop and many many more requirements. Why are you doing this ? I have proof of the original exercise however I cant seem to upload it on this feedback page.
