Bug

It is a bug report:
It is possible to get 2 pieces in the air (moved) at the same time. It is not possible to actually drag and drop 2 pieces but is possible to lift them off the board. This minor issue leads to a more serious one as once two pieces are dragged around other than moved pieces are being locked on the board for the rest of the current and all other games. Issue is resolved by rebooting app.

Steps:
1. Boot the game.
2. Start new game in any mode.
3. Using two fingers at the same time try to drag and drop two pieces at the same time (take as a bit practice)
4. Drop one of the two dragged pices into new location on the board.

Actual:
The rest of pieces on the board are locked. There is also cross mark on the board.

Expected:
Please make sure that it is not possible to drag and drop more than 1 piece at a time.
