Strange but I just seen at tomorrows Prestige missions a Total Cakestrophe mission. I thought today is the last day.
So now it is not clear at all, - for how long can we collect cake slices??
(If not today is the last day I might have a little chance to get all I need for the costume.)
If the event ends today, which they said it would, then I imagine tomorrow's cake mission will go poof. Just like when the event started, we magically got a cake mission for the very same day without first seeing it previewed in the "tomorrow" slot.
