Missions & Complexes

You've got it wrong DMC, re-read the thread the right answer is definitely in here.

I can categorically state 100% that the storyline agent does not have to be in the same region. This is not debatable or unknown - it is scientific fact. I know this because I tend to build up 9 or 10 7 SL missions a week before doing them all at once. My mission hub is in metropolis, but I get given SL's from an agent in the same system in Metro, then Heim, and MH as well the more SL missions I stack up.

The SL agent that the OP said was 1 jump away was in low sec in the same region (NOT IN A DIFFERENT REGION). Bearing in mind your faction standing plan that is so often suggested to people it is definitely worth making sure you are aware of the correct answer so that when you help others you give them the correct answer.

EDIT @ the OP thanks for posting the original question, yours (and subsequent posters) answers have massively cleared this whole subject up for me. The only thing I do not understand is how to leave an expired SL mission in my journal - when mine expire they just disappear. Not sure if I am looking in the wrong place, or potentially have checked a box somewhere saying 'remove mission offer immediately upon expiration'
