Everything Reset + More Problems

So I start up Halo 4 normally, and i see that the war games intro is playing i skip that and then it goes through the introduction of war games, and then my whole spartan is reset to default and i have like 300 starts in armory, and 50 in load outs and so on. And then i go into campaign and all my mission are gone and its back to prologue, i lost all my solo and coop legendary pictures too. This same thing happened to me in reach and i thought they would fix it but i guess not. And also when i go into war games i cant load half of the maps, like what is going on? is anybody else having this stupid problem?
