Halo 3 amor question?

[Creed]

My question is.I am trying to get the security shoulder armor. And it appears. But every time I try to equip i, it disappears. Then it comes back at random moments. ANy idea why this happens? and u know how to fix it?

it's just lag. the game does that a lot of the times for some reasons, but ironically not all people have this problem. you can try clearing your cache to see if that helps.
