Just tried to do what I think would have been a really fun DS where I was going to be presented with some real life scenarios and then have to perform a search and select which results were best. Unfortunately, after being presented with the first scenario and clicking the "Next" button, I got a message saying the connection was lost.

I did try to refresh the page, but it didn't work, and I did report the problem. Anyway, just wanted to give a heads up. Hopefully, this won't happen to anyone else.
