Aspirations Credit / Actor

I *think* this only happened when I got the fairy pack (which I think was after the major update / bug fix if I recall right)

So, my Vanessa (yes, the NPC since my Sim is romancing her to marry her) is a vampire and an actress (obviously).  One of the two aspirations (I think World Famous Celebrity)  requires her to get asked for selfies etc.  Because of that, I tend to go "bar hopping" from one world to the other - the idea being I see different sims and sim types.  For some reason, I keep getting the bulk of the sims that were at the other bar(s) even though I'm only moving Vanessa herself.  The kicker:   Other celebrity figures show up anyway and sometimes the game is taunting me because one of the other NPC actors get asked for a selfie.  I don't believe it's supposed to work that way and especially with other celebrities (several of the NPCs show up at once) showing up to "compete" to get that progression part done

Feel free to change the title for whatever best fits for it.  It's just a bit annoying/frustrating that basically same NPCs show up and follow you when you go from one world spot to another so you can't get the World Famous credit despite only bringing the one sim that you need to get the credit.
