Corrupted Save

I have a save file that crashes the game back to the desktop whenever I try to load a household.

It is a very large save file with about 800 sims (including NPCs) and does contain multiple very complex family trees. I also do rotational play in this save. One family in particular contains a situation where one sim has more than 25 children with 8 different partners, with most of those partners also having children with other partners. Monogamy is not a thing in my save! Also, many of my large families marry into other large families repeatedly. This was never a problem until the Royalty and Legacy patch.

I am currently rebuilding the save file from scratch, and I am making some cuts and edits to reduce the number of sims and the complexity of family trees. Since I can still load the old save file as long as I don't load a household, I'm saving off my sims to the tray to be imported into the new save file.

My concern is whether I'm just going to recreate the problem if I import all of my sims and recreate the incredibly complex family trees, especially for the one sim that had many partners. At time of writing, I've kept that one sim monogamous (with 13 children with his wife, and all of his grandchildren from them and their partners) during the rebuild and things seem to be okay. But, I'd like to eventually restore that one sim's children with other partners, 14 of them, and all of the grandchildren from them with other partners that I honestly can't count how many of them there are.

I'm basically looking for some guidance into how far I can go to rebuild the save file, and specifically how complex I can make a family tree before I cause a problem. If too many children are a problem, or too many connections with other families are a problem, I need to know those limits. If those limits aren't intended, then I hope I can help with a patch.

I am willing to provide a save file for analysis in addition to a LastCrash file, which I already know is a Stack Overflow error from my own analysis, and DxDiag should that be necessary. The save file will be a "Mods Removed" save file. I can explain more to the EA staffer that contacts me.
