Playing on Xbox One X and was in the finals tier of the TC masters international on the final section (level 1...tier 1?) I had done the first two sets of races and was doing the final races to finish that career path. I had done the first race at Sugoland and then as I went to continue, it gave me an error message saying that required DLC was not available? I have all the DLC installed, and own the season pass so am sure I'm not missing anything, I have double checked with the Xbox Store page and everything is installed as it should be.

So now the game thinks I haven't done any of that final career path at all, all progress is missing. And more to the point, I have no idea what DLC it may have been referring to? Cars or a track? Help? Thanks
