An Achievement or a Trophy Did Not Unlock in the Game
Reasons why an achievement or a trophy may not unlock in the game
If you have an achievement or trophy that did not unlock, double-check that you completed everything that needs to be accomplished in order to unlock the achievement or trophy. There are often several specific things that need to occur or be equipped for an achievement or trophy to unlock.
If you are sure that you have completed everything necessary and the achievement or trophy is still not unlocking, you will need to retry the achievement or trophy. Unfortunately, there is currently no way for us to manually unlock achievements or trophies.
