resuming sessions (like a race) via replay deletes the setup you had. This has become a problem for me as I wanted to make a endurance race in LeMans and the default setup is very slow so I have to resume before a pitstop everytime so I can kind of fix the default setup. Any way to fix this ?
No, the default setup is the same, I started from (default setup) there and made another one that I saved.
So if I always resume the original replay my setup should stay ok ? But then how would I progress on the session ?
Save and name your setup. Then click (select) that setup and click "ASSIGN". If you don't assign, it will load the default setup every new session.
I only race online and have never used this "resume from replay" you talk of so I cannot help anymore.
