Since I'm new to the game and racing in my first ever season, I've got a question to the more experienced managers out here regarding the Chief Designer position.
My 4,5* rated CD participated in the first 11 races of the season, but due to my level up progress, he slowly decreased in star value. I've now purchased a new CD suitable for my current rank to improve my design for the following season.
Do I have to keep my old CD in my team in order to maintain the progress he made throughout the first races or can I just sell him off the market to save his wage?
Cheers :)
