Stockfish places a rook out of thin air

I was playing vs stockfish at level 2 at move 26 the system does an illegal move. I also have screenshots of it. Stockfish lost both rooks but then places one on the board.

Please see lichess.org/variant/crazyhouse

Alright thanks

However, the Fish had one in stock.
