Error report

[Few minutes ago] After pressing “Find new game” I heard signal of “receiving” order but on screen appeared only timer counting since this pressing. There was no rest of “visual” interface, especialy no button “resign”.
Button “Find new game” was still accessible. I have used it for two times, and had afaik three separate processes of finding opponents. When I heard start of game (one process succesfull), I had to find my game between all other games because it was not “open” on my screen.
At end I had two simultaneously played games and probably third one which I could not find.

Another thing.
Please make it clear and straightforward: where to send bug reports?
