Until a few minutes ago, when one of our developers clicked the down-arrow icon next to their avatar, they'd see a useful set of menu items. Now, those have vanished – all that's left is "Profile" and "Log out". I'd do a screencap except that when I logged out and in to repro the problem, my account did the same thing.
No admin changes other than changing the lead on one project in last 48 hours.
