Does anyone else have this insane household bug?

Out of nowhere, my game started lagging insane lately. I do have a lot of mods but there was no issue until recently.

I didn't know what do, until I saw the households panel. What on earth is going on here? There are an insane amount of households with this exact setup of two adults, one teen and a ghost child??? No wonder my save is dying, this is mental.

I think I've also seen households with only foxes, which reminds me of the bug that came with Cottage Living, but that was apparently fixed since.

Does this have something to do with Life and Death? I'm kind of losing my mind over here.

I'll try taking my mods out, but the last time something like this happened it had nothing to do with it so I don't have high hopes.
