WTHeck do I keep getting d/c'd from 1-2 missions while I'm in a crusade?!! It never happens when I am playing other missions! Furthermore, why when I re-connect are the missions NO LONGER AVAILABLE, no matter how long I wait or if I've disconnected. Please explain and contact me via Xbox chat or email on account profile. This is VERY tedious. And before you suggest, it is not my internet...
