I made a puzzle today in the editor. After verifying it I wasn't able to start the upload, I'm taken to the 'Web Browser' button in the overlay and it fails to load a web page. To clarify, no web page is opened, the window is otherwise blank with a '+' button at the top, which opens a fresh web search page.
I checked the workshop, tried uploading again, and checked the workshop a second time. The puzzle is nowhere to be found.

I think my problem might have to do with the new steam overlay, anyone have any suggestions or solutions?
