iPhone: Wrong information shown in board position list when replaying moves and restarting games

[herzbube]

The problem affects only iPhones, not iPads.

Replaying moves

1. Start a new human vs. human game
2. Place a black stone on A1. The second entry in the list of board positions shows a move that places a black stone on A1.
3. Discard the move. The list of board positions is now empty.
4. Place a black stone on B2

Expected: The second entry in the list of board positions shows a move that places a black stone on B2. Actual: The second entry in the list of board positions shows a move that places a black stone on A1.

Restarting games

1. Start a new human vs. human game with 7.5 komi.
2. Terminate the app.
3. Launch the app. The first entry in the list of board positions shows 7.5 komi.
4. Start a new human vs. human game with 5 komi.

Expected: The first entry in the list of board positions shows 5 komi. Actual: The first entry in the list of board positions still shows 7.5 komi.
