PLEASE PLEASE FIX THIS BUG! i have been playing the halo franchise for atleast 8 years and have moved around a lot so havent always had internet to connect to xbox live , this basically means that before i get xbox live up and running i complete the campaign on legendary, however i did this on halo 4 solo and then after got my internet up and running and figured out that i havent actually got any of the unlockables that you get from completeing halo 4 on legendary.. :? why isnt halo 4 able to see that i have completed it ?just wondered if if this were a fault with my xbox or just halo 4 in general ???? :S its F%£&ing irritating"!!!!!
