Bug: Match continues after draw by repetition
If the system didn't give a draw by repetition, thee wasn't one.
The draw is a triple repetition of position and not moves. All the pieces have to be on the same squares each time, all possible moves have to be available in each position, and the same side has to be on the move each position.
In that game, black had casting rights until the king moved, so doesn't qualify as a repetition.
You played multiple moves past the one position where the draw the draw condition was almost reached. Did you by chance capture a screenshot of the draw condition showing? And it wasn't your opponent offering a draw?
