I've just had this happening to me in a ranked game.
And guess what, my rating before was the same after.
So the opponent resigns, the game is frozen and the rating is unchanged.
This seems to me a lot like the opponents are doing this on purpose.
Should be easy to reproduce, for example, resign and disconnect internet immediately after or something like that...
Requires invetigation because it happened a lot to me, and now I have understood why.
