Niana, each of the six black ops need to have different names. So if someone gets Share a Recipe as an opportunity once with Agnes Crumplebottom and once with Emma Hatch, you'd only be able to count one of them as the black op as I believe the opp is called 'Share a Recipe', not Share a Recipe with Agnes/Emma".
If even a single word in the title of the op is different each can count as black ops, but when the title is exactly the same, it can only count once, even if the sim/object it targets is different.
That's the way I understand it has always been, anyway.
