You play console so not sure what that has to do with this. I've been using MCCC since the beginning of playing TS4 so not sure why, just after downloading Growing Together, MCCC would suddenly be triggering so many deaths.
As I said, and I guess it needs repeating, I have had NO FRIENDS DIE in TS4 since the moment I installed the Base Game. So for 4 1/2 years, I've been blithely going about my business, enjoying the game (mostly, except for all of the bugs that never seem to get fixed by EA). MCCC was one of the first mods I installed and I've been playing with it, with all of the updates, for all of that time, with NO FRIENDS DYING. MCCC is also a major mod so, if there were issues, they would address it quickly.
I can't believe I have to keep pointing out that there are numerous posts on this if you Google it, not just on EA, where people are probably learning that finding help is nearly impossible. I knew it beforehand but there are no answers for it anywhere so I had no choice, and EA refuses to actually allow customers to get support for the products they pay for.
It is a big enough issue that a gaming website, on Jan 23, 2024, provided a "cheat" of sorts that allows you to toggle death off and on, BECAUSE OF THE EXCESSIVE DEATHS ISSUE, but you have to do it each time you open the game, which isn't feasible.
So, since the previous time I played the game and all 3 Sims I played each lost a good friend to DEATH - and I have no idea what kind of death because it doesn't say - I decided to try it again with an established family in a different save. This family has never had any friends die, either. Within 2-3 Sim days, I noticed the wife/mother was "sad" and checked the mood tabs at the bottom and discovered she had lost a friend. I had to go to her Friends tab to find out who it even was. So now, not playing again. Getting tired of EA caring so little for the Sims community, pushing out kits and "fluff" stuff hand over fist but completely ignoring the packs where there are actual gameplay changes and issues. It's frustrating, especially after hearing the horror stories of EA banning people for complaining, which is unconscionable. Except it must be true because EA gives you a list of topic you can contact them about, and there are several that refer to banning. Egads.
