Funny story: if you don't complete the Bomb mission within three missions of picking it up, it explodes. Which isn't funny, as it affects your war assets and stuff.

I'd definitely ring up customer services - ugh, I know - but seriously, they might be able to help you. If nothing else, at least you've then exhausted all your options that doesn't involve - ugh, I know - paying more money.

I still think this entire region thing is ridiculous, though.
