I’ve completed the “requirements” for the Summer, Autumn, and now Winter Seasonal Championships, and the achievements for none of them have popped. I’ve tried rebooting the console, deleting and re-installing the game and DLC, and even deleting and re-adding my profile to my console. No luck whatsoever.
What exactly are the requirements? Are we required to do only the three sets of races for the Championships, or are the other events, like the Co-op Championships also expected to be completed? Or, is this bugged? There are people on TrueAchievements that are having an extremely difficult time unlocking these when we think we’ve met the requirements:
