2.12 student HTML missing

Anyone else experiencing this? I have a few students in each section who’s websites seem to have vanished? They emailed me the links and I can still view them in my “Teacher View”, however when they login to add CSS the code is missing?

I would first check that they are on the right .html file. Often students will be on the wrong .html file and can’t find their work. If that’s not the problem, then I might go ahead and submit a bug report.
