Achievement 'Speedcross Champion' won't unlock | Xbox One

Hi there,

I ran into a problem I've ran into before multiple times, but this time, my usual fix does not work. The problem:

The achievement 'Speedcross Champion' will not unlock, despite the fact that it even says on the menu>journal>speedcross that I have gotten 100% of courses completed.

It may be due to the fact that I completed the questline when I was playing in offline mode, because my NFS Payback crashes 19/20 times when I do play online.

Finally, I have gotten the game to run after several tries (and by using an extensive workaround that works 50% of the time) when connected to EA online.

I was able to unlock 3 of the 4 new achievements, since those were simple, but also because I hadn't gotten them when playing offline yet.

Now, how do I fix this? By replaying all speedcross events?

In other cases, like the one percent club achievements, I had to replay only one event online to trigger the unlock of the achievement.

I have replayed 4 of the speedcross events now, including the final two (defeating barracuda and the runner up to that event), it did not trigger the unlocking of the achievement though.

I'm eager to hear any solutions to this problem.

Cheers,
