You know, just thinking about it, I have never seen any popup like that in MCCC or the game. Are you using any other mods that affect relationships and moves, marriage, etc. autonomously?
Are you sure you have Neighborhood Stories turned off for that household. NS doesn't marry sims afaik, but it certainly will move sims and generate babies and adoptions if you have it on. I'm not sure if it will move sims in together now as I have it shut off. I haven't used it in a while, but I did try it for a while but didn't like the chaos it was causing in my save so I shut it down for the most part. Now I only have it on for the NPCs in the Other tab and only the deaths even there just so I keep getting the NPCs changing over.
Hope this helps.
So I think I may have been given the solution and I have now set the relationship move-in percentage to 0. It is the next sim day, and I've had no pop-up to say my sim has moved out with one of his boyfriends or girlfriends 😀 .
As long as the sims in the surrounding worlds continue to get married and live their lives, I think I may have found the solution.
@luthienrising I checked on the MCCC discord help server, and was given what I think is the solution - I suspected it was that mod. I played for about a sim-day and didn't get the pop up again, when I took their advice. Yet to go back in to play for a length of time (don't have time to do that right now)....But I assume it is now corrected.
