Auto-advance on the IBB missions is obnoxious. Recent game got to a very slow start - bounties in inconvenient locations, nobody had any good destroyers for sale, etc. - and the IBB missions keep skipping ahead to ones I don't have a realistic shot at completing.
If I'd known it'd stop advancing on taking a mission, I would've just grabbed the first one and let it run out of time.
As it is, well, I expect I'll be taking advantage of console commands to reset the thing now that I've finally gotten something resembling a decent fleet.
