Sudden change in Chimaera VS Leviathan counter

I usually get sandwiches every Sunday at this place right next to CGs office. Usually it is empty on Sundays, but today there were a bunch of guys walking out of the office high fiving each other and laughing. I couldn't hear exactly what they were saying, but it was something like "He'll never see this coming! He's gonna be so mad when he tries to climb in fleet tonight! Nobody expects the Sunday Nerfquisition!"

Maybe that has something to do with it?
