Problems? Plenty of them

Has anyone else had any of the following problems?

First, trying to buyva car from the auction house. Bid was 12,000, I had 2,400,000 credits, game says I don’t have enough. Come out of the auction house, my credit balance has dropped to 1,666,000 credits.

Second, spent most of yesterday getting wins on all the Street races, and 3 stars on all the v10 story missions. Fast travelled to start getting 3 stars on vocho, game crashes to dashboard, when I restart, all street racing and v10 progress is gone.

I was enjoying this, but this has just put me off bothering with it any more.
