He, since the latest update, the one that added the branching dl's, my records on some tracks on TC have disappeared. The thumbnail on those tracks also now have a +xp icon in them, inluding some other tracks.
I've only checked my own tracks and some on the Uplay Recommended, but it seems to be random. Tracks include: My own tracks in the featured feed Dirt & Dingoes, IcePiercer(I replayed this track, so my name is there again, but the +xp icon is still there)
And the Uplay tracks: Includes atleast Deep Sleep and Antiquity.

And also Nocturnal and Ravaged World and a couple of other tracks have an +xp icon in them, but my records have not been removed.

It's not really an issue for me, but I was just curious how they got removed and what the +xp icon is. Haven't seen anyone else adressing this so I thought I would make a thread about it.
