Have lost my credits few car and XP on online freeroam.

So, I’m on the Goilath Circuit, like 6x 1 laps.And when I went to the garage , I’d wanted to auction my cars, an Audi (Horizon Edition) and it freezes. A few minutes later I quited the game, and opened it again, and it hasn’t saved my data.Can somebody help me about the CR and my cars? Thanks.
