Weird notification?

The generating tickets one showed last night for me (while my castle was still building, but I assume its related to the upgrade). I clicked it and when I went to Krustyland all my people had tickets above their head. Just got the notification again now and haven't logged in but I am expecting that's what it is.

So it appears we are now being notified when the tickets appear on the visitors in KL.

EDITTED to add that once again, upon visiting KL, their were tickets above the visitors so I'm positive that's what that notification means.
