I just saw a player, "Runean" in MP whose name did not show up in the "Players" list on the left. Runean was playing with "owangolama" (match listed in results as 2014-02-12 00:25). I clicked on the match and it was being actively played so Runean had not dropped out (he also won the match). I clicked the "Rating" button and the name did not show up then either. Also, a bit earlier, when Runean still was over 1,500 in rating before losing to Beledorf, his name did show in the list, I happended to notice it earlier. It disappeared when he dropped temporarily below 1,500, while I was playing a match myself.
