Re: my game "battlefield 3" disappered from my origin game library.

Hi there,

This is not a problem.

If you have bought and installed the game, you can find the game under your download history. Go to settings > Account > Purchase*/Download history. From there you can find every content you have downloaded or installed. Games, videos, DLC etc.

If you still can't find the game, please contact Xbox LIVE support.

- With kind regards,

  Timmie.
