After I castled something happened, and my K was on d1 and my R had disappeared. Please compare the final position from the pgn with the screenshot attached.

a known glitch

how did you post the game?

Paste the pgn between pgn tags .

thanks -- I find this glitch happens in 960 here about every 30 games or so (usually just the one rook, but, sometimes both rooks vanish on castling)
