Achievements unlocked but not added or showing til I go into game?

[Mod removed- inappropriate]. Ive never had it happem this way. I have the notificationnit unlocked but doesnt reflecf on gamerscore or outaide of the game.

Try signing out of your Xbox live account and then sign back in while in the game. This is a pretty common bug with achievements. Sometimes it just takes a while as well (few days)

Same stuff happened to me yesterday. I unlocked an achievement in Red Dead Redemption on Xbox 360, it popped on the screen. When I look at the list of games, it shows I unlocked 71/95 achievements in the game, but when I click on the game to show all achievements
in it, it shows 72/95. Interestingly, as soon as it unlocked, I opened up the list of games and it was correct, but after a minute or so when I checked again, it was messed up. Similarly, it's not added to my gamerscore too.

hello, i have some problems with unlocked achievements in Rage game. I have 4 achievememts from it, but the last 2 did not counting. On the xbox dashboard it shows that i have all the points from 4 achievements, but when I go to achievement section it shows
that it's only 2 unlocked, but i have 4 of them and the points are not counted from these two, but when you go to the Rage game there shows all those 4 achievements that i had unlocked. Also, here on the website, on my profile the points are not counted, but
it shows that i have those achievements unlocked.
