They did not. 12x365 = 4380. Note that the daily rewards surrounding day 4380 are not Devil Dino and the other limited 4s along with a bunch of nice extras like 25 CPs etc.
That means the new Devs who are adding the daily rewards aren’t aware that every 356xX (where X is number of years) gets a special set of rewards around that time so that when each player reaches their individual yearly anniversary they get those rewards and realize it’s been another ‘year’ playing MPQ.
