An issue with our old Gerrit caused some device repos to get reset to a month back, which is probably why some people are experiencing some weird issues with their devices. So for now either stick with a nightly you know works or be prepared to have bugs on newer releases until we get it fixed, which might be a few days since we have to go device by device and bring them back up to date (and since most of the devs are inactive over the weekends :P)
Also, I (PR Dude of Carbon) will be gone for this weekend and probably won't have internet access. So you guys have to fend for yourselves for a little while. Help each other out and be patient with one another. Hope everyone has a great weekend!
