I saw another important thing too. It was end of last year, time of the big freezes and slow buttons. Something changed, and the lobby was much faster. I played on an Aquarium table. All Ins on all preflops. Two players had 400 chips on table and went all in, the other players folded. What I saw then next (!): On the table preview on lobby had the one of both 0 chips on table, the other 800 - rake. On preflop! The software knows on preflop all tablecards and who wins (on All Ins). What we see then on table (flop, turn, river, winner) is only an animation to see the hand go to end. And on this part of the software goes something wrong, sometimes it ends on turn and shows no winner. But it gets right saved to the database for hand replaying, no problem there.
I learned application developing and know what happens behind the curtain. But I learned not web developing.
