I have a problem making two former siblings full-siblings again in a new game. This is what I have done - I hope I can explain it alright.

I have manually moved 2 households (via the Library) from one game into another (each in their own group). I know that Porter has the option to move Sims in an easy way, but there were specific reasons for me to do it this way. In one family was the sister and in the other family was the brother.
Before transferring either to the Library,I had located their parents' graves with MC and put them in the brother's inventory. I figured I could easily make them siblings again, once they were placed in the new game. Not so.

I don't know why but I cannot make them full siblings like they were before - MC only makes them half-siblings.
The brother with the graves in the inventory (I placed those in the town as soon as he was moved in) was showing the parents in the family tree. When MC makes the 2 Sims half-siblings, I cannot see either of the deceased parents in the sister's family tree. I tried with Add Sibling, controlling first the one, than trying with the other. I tried from the lot and from the town building. Then I reloaded and tried to add (the deceased) parents to the sister. They don't show up as an option. Via Find Grave I could see that the parents are in the game as deceased, so why don't they come up as an option?
Something odd though was that the parents seem to be there twice! One set at the graveyard, where I had placed the graves from the inventory. And another set which I was told existed in someone else's inventory, and if I wanted to move them into this Sim's inventory (the sister) instead. Trying to do Total Innialation on the extra set of parents who don't exist at the graveyard is not possible - it tells me they are not instenciated or something. I tried saying Yes to get the graves into the sisters inventory. I deleted them with debug, to see if this would help. But no.
I didn't save any of these attempts. Hmmm. Anybody know what is up with this?

Edit: I guess I should mention that I used awesome mod's TheRapture to empty out this new neighbourhood before moving anybody in.

I don't know if this could cause issues, but you can empty out the town also with MC -> town -> total anihilation

Maybe check first when placing both families if there are really other graves in the inventory of a sim

What about placing the graves oon the lot ground, use Debugenabler to spawn the ghosts, both, and then use MC
click the ghosts and use Add child.
Does this work?
If not maybe give the ghosts the relationship married first (they loose it when death).

In one family was the sister and in the other family was the brother.

Why didn't you merge both families for transition as one household to save to the library
and divide them after you have placed them? I think this way you maybe don't need to take the grave too.
I assume they still will be sibblings.

The reason is, each sibling was friends with different kinds of people which I liked. So I decided to put each sibling, their spouse, children and their respective friends into each their own group. If I had taken them in one group, Porter would make all those in a group know each other, which I didn't want. And I figured it would be easy to make them siblings again in the new town.

Awesome mod's TheRapture should erase everything completely from a town (as far as I am aware) and thereby avoiding any lingering stuff from what was in the world before. I guess the equivalent to "total anihilation". Which is why I am puzzled what is going on.
When I created the different groups I double checked who had gravestones in their inventory and there deffinitly was only one pair of the parent graves - those in the brothers inventory. I sure don't know what is up with this LOL.
The question now is, what do I do. Ideally to make them have the same parents and get rid of the extra pair of dead parents that MC tells me are there (although not instenciated, or something like that). I don't want to create more mess now, rather less LOL.
If nothing else, how could I get rid of both dead parent pairs altogether - I have tried to do "total anihilation" on the pair which is not instenciated but that does not seem possible. :scratches head: This was supposed to be a 'no brainer', haha.

You missunderstood me, I didn't mean Porter. I meant that you like add with MC second "household" to the lot with group 1 and
in edit town save this family to the library. I don't think that any friendships to sims in your town are kept, only the relationships that ARE there at this moment, and they keep their careers and such.
In the new town you can split the families to move them to other lots and they should have kept only their previous status of relationship or relation between the sim from this household you placed from the library.

No? then do the step with taking the ghosts too and spawn them, then add parent to your sibblings.

I think MC town -> Total Annihilation does this?
Filter Type of Sim (Or) -> DEAD

I managed to find a way to totally annihilate the false set of dead parents, and the brother is showing the real ones in his family tree, yay. Less mess.
I tried every way with the ghosts to make them the parents of the sister too, but it wouldn't work properly - not everyone got attached the way they are supposed to. I even resurrected them to see if that would change something. So I am thinking of leaving it the way it is now and only think of the former brother/sister as distant relatives that the game cannot show. I don't want to risk screwing things up by trying to make them related in a broken way.

It would be easier if it was possible to actually see what one is doing, like in CAS where you can shift the thumbnails of the Sims around when making them related. And then generate a preliminary family tree where you can see who is now related in which way (whole/half, in-law...), before accepting it.
Main thing is the game can move on in a healthy way. Thanks for all your help. At least I got to test some possibilities which I hadn't before, which is always nice if you have to leave things in a not preferred way.
