Almost right after I started playing FM6, I noticed my rewards had the showcase events maxed out even though I had only done one showcase event. A couple weeks later, I noticed my Gamerscore ranking was way below where it should have been. I thought it was just behind like it so often is, but I put 2 and 2 together and found that for some reason, my early Gamerscore points went towards my showcase score. Now that I installed the Forza Hub on my laptop, I can confirm because it shows I completed 147/30 showcases. For reference, it is showing I only have 375 on my Gamerscore even though it should actually be 690. Is there any way someone can look in to this and get it fixed?
I doubt your rewards are any more broken than anyone else’s. I had your problem with the showcase events maxed out when I first started playing - I wasn’t complaining about it of course because it meant I was getting closer to my Tier boundary. It never occurred to me to compare it with my Gamerscore points.
