Are you able to provide a screenshot or example of what you're seeing?
The levels can sometimes be a little misleading - i.e. if you achieve a certain mission or badge, there are different points associated with those, and some may pop you into the next tier or level. It's something we're aware of and would like to address or potentially "fix". I'm definitely open to any ideas you may have!
Mine seems to be intact.
It's working now If I see it again I'll take a screenshot, but just imagine no "level number" below your avatar, and no details re/ level, points and badges in your profile.
Screenshots ... maybe it's a backup/recalc thing because everything is back to normal again now.
