Hello, I tried to do a Multiclass Race offline. It seems as the Brazil Stock Car Class is always stuck and I can't run a race without it. For example I would like a GT3/GT4 race and I always get Stockcar/GT3/GT4. Anybody else having this problem?
I have found that the game seems to remember which classes you had previously selected when you go to multiclass racing. Have you tried selecting GT3 as your class, then going to "Opponent settings", set the class type to "Multiclass" then the four boxes should show up underneath, click any of the boxes and it will bring up the class selection screen, hit "Clear all" and you should be left with just your selected class of GT3, from here you can click up to 3 other classes to select them. Not sure if that helps or if you have tried this already.
