Okay, another *small* thing, but I thought I should mention it in case it's a symptom of something bigger.
My unrated game has disappeared.
What I mean is, I had played & finished 1 unrated game so my Total was 1 more than my Rated. Now they're equal.
Somehow my unrated game is in the rated count - it says 43 but you can see from the graph in my profile that I've only played 42 rated games. I've cross-checked all my finished games and the Total is right but the Rated is wrong.
