Ive been in 2048 withdraw since the iOS8 update. The update has fixed the crashing issue (yay!). I do have a weird glitch now where a tile slides all the way off the board and then stays that extra bit away, as if there is an invisible tile in the way of sliding. It actually still combines with the tile it should and the first time in the game I kept going and it fixed itself but then it happened a few more times and just really throws things off. As soon as that gets fixed Ill be back to spending all my free time trying to beat my current high score!
