super ficha said:New challenges have been discontinued but you can carry your PC time back to or before July 31, 2021 and access earlier challenges. I highly advise that you do that. If you want your achievement time stamps to carry the real time, start the game with an old time and change it back to the right time during gameplay. Finish the challenge. It should go through. Close the game and open it and the effort should count towards the stat data. Try it and let me know how it works.
For the Center Stage achievement and other Daily Challenge dependent achievements, start game with an old date and play. During the challenge, minimize the game and change the time back. Achievement should pop when you are done. Of course, if you do not care about time stamps, you can do everything with an earlier date.
