Well, my 6th overhaul is uploaded. It is adult oriented, so I can't post a public link here. But, with that said...most of the "adult" stuff can be turned off (not all of it) so it becomes mostly optional. If you turn most of it off, you'd actually have to purposely choose to see the adult stuff. Though some "adult" npcs are around, like slaves and what not...cause nordic/vikings/medieval people always kept slaves anyway. So more realistic (though makes it adult since that isn't a child friendly thing to see in the politically correct world). Definitely not a kid friendly overhaul.
A 62 hour played character, with only a 14.8 mb save (that is REALLY small for a huge over 200 mods, many with heavy scripts, and a long time played character)...no real issues. However, most of the time...I have to load an old save I keep as a backup, and THEN load the most recent save. Though I just started up and game didn't automatically close on loading the recent save (no error message, just closes). But, other than that small thing...no save breaking or game breaking issues.
And I just got done with a huge description of the mod on Loverslab, and I'm about to go to bed. So if you want a link to the mod+a link to the mod page, feel free to send a PM.
I will say, it isn't really focused on adult stuff (its there, and I mostly put it there cause why not. Heck, I honestly leave most of it off, since I prefer playing). There is a TON of gameplay, and a ton of new stuff. All the "adult" stuff isn't really a big focus at all.
If you send me a PM, I may not get to it that soon. It is christmas eve tomorrow and then christmas...so gonna be spending most of my time with family. But, you may be able to find it anyway over on loverslab if you want to go there. Or I can just send you the links through private message.
