Hi there! I hope this is the right place for a question like this.

I don't seem to be getting the achievements for Ziara Raceway such as the one for a score of 4500 or wins (besides the win on hard mode, since I haven't been able to win that yet haha).

Any ideas why?

If you've earned the achievement but aren't getting credited, I would recommend submitting a ticket. Some might be retired, or only available during the initial event, even though they aren't marked as retired. Or it could be a glitch. The only way to know for sure is to submit a ticket.

You could also try looking in the bug forums, I think there's an achievement thread stickied, to see if those achievements are known bugs.

Thank you so much!
