I called Xbox and spoke to a number of people and they were able to verify that but. what weird is my online stuff in Halo Wars is still there. its just my offline achievements that got deleted.
This is opposite in too other games. My online stuff with them is gone. The guys I was talking to at Xbox live were able to help me deleted the corrupted files (over 12) and that is on file but how do I get back what I lost?
