I think the issue was happening because we didn't disable the buttons which add a new view,
after we were using them once.
So the user was adding more than one view when clicking more times.
Check the latest changes at here and re-inform this issue if it is Fixed.
You can start a game with the timer stuck at 0. Step1: Press "New game" Step2: Triple click any game (ex "Easy").
I tried this on Windows using the "Minesweeper.exe"
