I rented halo 3 back when it came out, and i didnt have xbox live, so i got as many achievements as i could. i found all the skulls, terminals, and i beat the game on normal. With ODST just coming out not too long ago, i rented that, and when i popped in the multiplayer disc, i hardly had any armor. i lost my hayabusa face, body, and shoulders, as well as my scout shoulders. i still have all the achievements for the "were in for some chop" and the skulls too. It didnt bother me all that much, but i got hooked again and decided to go out and buy Halo 3. When i was going to play the campaign, it said i never even started. i dont have any of the levels or skulls unlocked, and i have the achievement for beating it on normal. Why am i losing all this stuff?
