I've send four mod messages earlier today (busy morning) and I've just discovered that my fellow Programmers mods didn't get the usual "Yannis released the Kraken again" header notification for any of the messages.
Don't know if that specific notification was supposed to be in the new notifications tab in the StackExchange™ MultiCollider SuperDropdown™ or stay in the header, but it's nowhere to be found regardless. Other than my four messages (that included two suspensions), we've just tested it again (you know, for science), still no notification. The messages can be seen in
admin/users, and the suspended users are, well, suspended, so the only problem appears to be the missing mod notification.
Well, no notification for the user either, as our guinea pig @BenBrocka reports (thanks ;). That's kind of a big deal, and makes this a bit more urgent than I originally thought.
I've just got a notification for a mod message, yay! And with another test suspension we've confirmed that everything is now back to normal at the user's side, thanks @Lix .
