There are also some strange premove issues - not sure if just 3d sets. Testing this (while my rating tanks :)) I have seen two variants:
- premove not set-up/locked: I make the premove, but the squares are not highlighted accordingly and the move is not made. This is especially bad in time scrambles when I think my premove is locked and then get flagged.
- move is made even before the move arrives (pre-pre-move?!)- this one is hard to describe: in
http://en.lichess.org/7d7I6lnS I premoved bg2 - now of course that is a blunder (after bxf3, bg2, bxg2). But what was weird was after my premove was made, it was STILL my turn :S So I see my bishop on g2 and I tried multiple times to take the bishop on f3 (and nothing happens). Realizing its a glitch, I refresh, see my bishop really is on f1 still, so resign.
Will try to isolate exact circumstances this happens in; so far hard to do because its usually during high-speed moving.
