As the title suggests, I've done at least 4 runs of Zero Hour (expert) where we have gotten to the end, killed all the ads + boss (even gone around and vaporised any dead fallen in case they haven't registered as dead) and it just won't complete? and because it wont register as complete I can't complete step 3 of Outbreak Refined 2+3; "Complete the Exotic mission "Zero Hour" on Expert difficulty". 😥 Please help! 💞
