Hey guys, I have spent a few hours trying to get some Halo CE missions done on legendary. I completed 4 in total today but only 2 of the 4 counted. The missions, Assault On The Control Room and, 343 Guilty Spark did NOT count for the achievement progress for getting all missions done on legendary. Now I’m going for the Legend achievement and checked that progress as well and it told me 18/40… Now I have done all the campaigns except Halo CE on legendary and have the achievements to go along with them (Halo 2, Halo 3, Halo 4) I should only be missing 6 since 2 of the 4 missions didn’t count. Just another thing I noticed was that I checked my progress on this website and it says I have them done. Can somebody please explain this to me? I might just have this “Legend” achievement all messed up but I know that these 2 missions not counting is some form of bug. Many thanks!
