hey may I pop into this conversation?
I had that error pop up as well a few days ago actually, and I am wondering whether it is connected to pets going missing.
The last time I played said family, their dog went missing. I then saved and quit, played another family the next day and stuff.
when I returned to that family, the error 131 popped up.
I was curious, so I loaded the family again.
Everything worked fine, but the game threw a LastException that I am going to attach here.
Yes I use Mods, but I am totally aware of stuff working (I'm with the MCCC support crew, whew).
And I know that there's a mod in that LE that you won't like. Just please take that LE as a first note for now, I'm gonna try to bring a vanilla one as well.
Another thing that is the reason why I suspect 131 and missing pet to be linked: The dog is still grey-ish in the little picture menu in Live Mode.
I can't take him to the vet (he is sick) because when I am there, it says that I need to bring a pet.
I can't even use debug cheats on it, they will apply to my currently played sim.
Next thing I am going to do is see whether I can reproduce that error vanilla, just to be sure it is an EA error. but since people reported it here, it seems like it it.
