Maybe an April fool's ???
Oh wait I just got it now , the roadmaps only the stuff that's gonna be added into the game during those months , but not what's going to be published... So basically no updates untill the end of the year.... Yep... Last update was in January but there wasn't any updates for this February even tho "there should've been one" but really there isn't going to be anything published until the end of the year.
Anyways yeah... OR MAYBE I'M WRONG and they're just taking some time and updates come every "seasons"
