How to force a dev release of my module? Whenever I go to create a release for my contrib module, it gives me one option - 6.x-1.x (6.x-1.x-dev) - but if I select that it says "The version you have selected (6.x-1.x-dev) is already in use by another release." IIRC dev releases are packaged automatically every twelve hours, so why is this option even appearing? And it seems like dev releases aren't being packaged automatically for my module ...
In the "Release" tab of your project you've a checkbox with "Show snapshot release". If you check it, you should see the dev releases appear.
