Yeah this part is mad frustrating and I would have thought with all these back to back updates and tons of feedback they would have changed it by now, but nope. Smh come on T10 please address these few crucial issues in freeplay already.Another is that when you specifically lock the car selection to a specific division, if you remove upgrades under "Car Restrictions", it then returns it to selecting all the cars in the game rather than all cars in a specific division.
We want to race with cars in certain divisions without the homologation (like the purely original versions). Either they fix that or add it to the race settings under a category called "Homologation: on or off".
