The easiest way to keep the MCCC story progression from affecting sims you don't want it to, is to keep them marked as played with the bright green plumb bob. And if you have Neighborhood Stories enabled for played sims, disable it in Manage Households.
Hope this helps.
MCCC will still affect households in the played section if they don't have the bright green plumb bob. If they have the light green plumb bob, MCCC thinks they're fair game. The move into together is MCCC but the pregnancy could be either MCCC or Neighborhood stories.
There is another way it could have happened though. Those phone calls that you get asking (I found a ring in so and so's bag) should I get engaged/married and should we have a baby? Both things will cause what you had happen. But you have to choose on those, and it would have to happen twice. I know I have inadvertently answered several of those the wrong way. Do you remember getting any of those calls?
Hope this helps.
That sounds like a plan that will work. But, if you have to do that for every sim, then it's going to be a bunch of extra work if you have a lot of sims.
You shouldn't have to do it though. I use MCCC and it took me a bit of experimentation when I set up a new long term save, but I was able to stop things like that from happening. At first, I was having move ins, marriages and babies. Now I don't have those things going on. So, it can be done, just takes a bit of time to get it right. You might want to experiment with the main settings a bit to see if you can get to that point as well. I used a throw away save to do it so I didn't impact my main played save. But it's your game so you do what you have to do to get the game playing the way you want it to.
Hope this helps.
