You did all the basic troubleshooting, so only contacting EA is left. Somebody else commented about the same situation. Furthermore, there's even a thread on EA forums stating the same you've written here. So while it doesn't seem to be as widespread as others glitches, it's not just an isolated case. It's either wait for the fix or pester EA to increase awareness (and still wait).

On the "good" side, A Prickly Obsession is not a limited-time quest so you can complete it even after the event's deadline, though it will be 24h instead of 3h by then.
