Thank you. I didn't share my replays so it doesn't appear in my activities. At least most of my 1st places was uploaded to youtube. It's very annoying to lose everything you like so much that you saved.. very angry.with PDYup happened to me too roughly on the day of the update; gone but oddly can still be accessed by going to your activity thread (IIRC) and not the gallery.
Also a lot of thumbnails to car/helmet/suit liveries are gone. They are still selectable, but no thumbnail.
Another thing is that times set in time trial mode are not carried over, so every time I race a track, I set a new best time.
