Showcase Achievement does not work.

I have finished all showcase races in career, even those in forza drivers club. But the achievement not pops up. Somebody have same problem?

Did you finish enough races in the Forza Driver’s Cup to unlock all the extra showcases?

Have you competed the Forza drivers cup ? If not once you win the cup more showcases appear. Really really long ones too. 300 miles of Sebring. 250 miles at Le Mans. 3 hours to complete each. Approx.

Hope this solves your problem.

Then i was too fast. didnt finish the drivers club - only the 4 showcases shown up. Thank you very much. Now i know what to do
