Notifications not working

Seems that notifications break down every once in a while and now seems to be another case of this. For a couple of days now I've seen no new notifications of people replying to me but I have seen threads and comments sections where folk have in fact replied or quoted me.

I thought this was because of the GB Turbo plugin but I've tested it on other browsers without it and also have seen no new notifications since Jan 1.

@humanity: Do you get this notification? Engineer says this should be fixed now!

@rorie: Weirdly enough I've been getting them on and off since I made the thread - some I've seen come through, others not. This one I got so maybe all is well now?
