I've been seeing other people having the same issues as me losing all online progress.

I was in the garage doing a livery when the game suddenly dropped out. I restarted the game and noticed all my money earned gone and only $20,000 left as we get at the start of game.Then I noticed I only have access to my garage, second hand dealership & Cafe. All my cars are there won and bought. All my cafe booklets completed with all my gold trophies. And I was put back to the very start of the game setup having to sink the picture and then going back to the music driving test. And now I'm locked out of all online menu icons. I can't do any racing at all! Only garage, Cafe, & 2nd hand car dealership available. My ps4 online name is That_0ther_bloke ,Nickname - Davo
