I was having trouble performing the because you begged challenge, and I followed a guide for pc where you have to delete a folder and turn off sync and this. This had the side effect of resetting my armor, skins, nameplate, icon, clan tag and service id. But it keeps resetting them even after I completed the challenge. Every time I launch the game It asks me if I prefer Keyboard or Controller and all the previous things are reset. I have uninstalled and reinstalled the game, currently only Halo Ce and Reach are installed now but the problem still occurs.
