Interesting. This was the first thing that happened - all cars in the Exclusive series had all their upgrades lost, and consequently all the Exlusive series were locked even though I had completed 50% of the different series.

I actually think the body upgrades disappeared at the same time but I didn't notice as I wasn't doing much upgrading because I had just taken advantage of the Xmas specials and was completing series with newly purchased or upgraded cars. I only began to notice when I started going back through series on 75% to see which ones were now worth going for the 100%.
