So I went through the "Select a custom Creative Commons license" selector to pick CC-SA-unported and when I was clicked "continue" I was thrown back on the page with "Choose which Creative Commons license you want and click "proceed"." (never mind that I had clicked "proceed" in the CC picker).
Also it forgot which extensions I selected to have enabled so I had to re-choose them.
