Fallout 3 has disappeared from xbox

The amount of points doesn't change the fact that you can hide the achievements, you can try this also

Please perform a power cycle reset, follow these steps:

Unplug the power cable from the back of the router, modem, or gateway for 5 minutes. If you have a router and a modem, unplug the power cable from both devices.

Restart your Xbox console. Press and hold the Xbox button in the center of your Xbox controller to open the Power Center. Select Restart console and then select Restart. (If the console appears to be frozen, press and hold the Xbox button on the console for 10 seconds, until the console turns off. After the console shuts down, touch the Xbox button on the console again to restart.)

After 5 minutes, plug the modem or gateway in first, and wait for all the lights to return to their normal state.

If you are using a router, plug in the router and wait for all the lights to return to their normal state.

I have 1000 points of achievements so you can't hide the game. And it's just not me, I'm looking at other profiles and no one has Fallout 3, it's wild.

I am using the same account. But before I joined Xbox live, I had a whole bunch of achievements in Fallout 3 and Fallout New Vegas. In Fallout 3, one that disappeared was one I remember most vividly. "Those!" was hysterical because I used a grenade to blow
up a giant ant, it flew up in the air, landed on a shed roof and slowly slid off, almost like it was using real physics when sliding. "Those!" is one that disappeared. I beat both games and even restarted both going in a different direction but now Fallout
3 says I only have like 3 achievements but I had most of them. Idk... Just a little annoying that they all disappeared.

Yes. I played offline for about 2 years. But the worse part is that in both Fallout games, the achievements disappeared from my console as well. From Fallout:New Vegas, I only lost a few, I can deal with that. But most of the achievements from Fallout 3
have disappeared. I was just wondering if anyone else has had this happen and may know the cause. Also, I have unlocked some of the achievements in Gears of War but the game doesn't even show in my list, let alone anything I unlocked. Thanks for any insight
you may have.
