When you get the error message: failed to save data. it's caused because you tried to save a replay that was too long.
After this you can't save any data anymore: like car set ups or progress etc.
You can solve this problem very easy without having to reinstall the game or hard reset.
Fix: Just go to your highlights and you see that the game has saved the "bad" corrupted replay.
Just delete this replay and everything works just fine like before your attempt to save this replay.
I came along another problem.
I can't adjust the steering deadzone (steering wheel TX) in steps of 1 clicks. I can only adjust in steps of 6 clicks.
the odd thing is when you slide the deadzone to the max, and then back it will stop at 4 clicks. And after pushing the red B button to save it becomes 3 clicks.
3 clicks is still to large. I want it to be 1 click.
Is there a work around?
