Ive had enough with this campaign. Ive slaved and slaved to finish it on insane difficulty and when i finished there was no achievement for it and it says i never completed the campaign. Then i went to the level select and for some chapters it says i never completed on insane it says i completed them on intermediate which is bull$&@$. Im very disappointed, as it took forever and a lot of frustration to finish this campaign. The new update made the game more stable to play but the achievements are still screwed up.
