keep losing my saved contents !!!!!

hello guys,

I need help…I am having issues when it comes to having my profile and armor saved. Every once in a while, I got to
re-equip my armor and emblem with colors…my biggest issue though is that I finished 90 % of all the campaign on heroic
and today I had to start from scratch again. I’ve been into gaming since I was a kid, so I usually know how to use the system.
so can you give me some advice in order to not having to play the same campaign over and over again !??!?!?!

Well this is curious. Can you give us more specifics?

Were you playing online/offline?
Did you disconnect from Live if you were playing online halfway through the session?
