Not sure if I'm putting this in the correct category but here it goes, hopefully someone can help me.

I googled about moving sims between neighborhoods since I'm trying to do my own from scratch and the first custom map I used turned out to be to large. The guide says to extract the sims I want to move using SimPE and then going into CAS and just remake the family. Now to my issue...

Only one of my extracted sims seem to be showing up. I went back to SimPE and checked if something might have gone wrong, but no they seem to have extracted properly (if I press save it asks if I wish to overwrite) Then I noticed this little text on all of the sims that said the appearance will be changed. Well the whole buisness with moving them from my first neighborhood was so that I got the families I've already made not having to remake them from scratch. Apperently they are supposed to be in my premade sim bin but changed to such an extent that I can find them at all. I have about 30ish sims in my adult simbin. The teen female one only has two but none of thoose look remotly like the sim I made. The sims in the bin is white with brown straight hair, and blond with short and the sim I made was black with afrohair.

Is there a way to get them into the new neighborhood keeping their original apperances? Maby by using another route. They have no ties to anyone exept amongst themselves. Since I have about 100 different skins and eyes and I don't remember which I used on the sims remaking them from their current state would probably be about as hard as trying to remake them from scratch. Is it possible to maby simpack them and install them or something like that? If it is please post link to guides or explain how I do It. Otherwise I'll have to try moving them trough the lots bin and since that can destroy my neighborhood that I invested about a weeks work on I don't really want to risk it but If that's the only way is there a way to backup my neighborhood in case it goes kaboom?

Moving occupied lots will destroy your neighborhood, so don't do it. There's no risk involved... you will completely destroy your neighborhood. 100% certainty. If you're going to destroy your new neighborhood, why bother creating it in the first place?

If you're just unhappy with the neighborhood map, you might want to consider keeping your neighborhood and changing the map using the HoodReplace program (see my profile). Or, is your original neighborhood bad?

I don't understand why your extracted sims would change their appearance. The entire purpose of extracting sims is to clone their appearance. Do you still have all of your CC installed? Did you clone your sims in BodyShop to clean them of all references to your previous neighborhood?

My guess is that you are looking in the wrong place. Extracted sims will not show up in the family bin, but will show up in CAS or BodyShop.
You are misreading the message. That message is telling you that the selected sim will be modified IF you perform sim surgery on them. Since you are not performing sim surgery (but are just extracting their appearance), they will not be modified.

No I didn't misread the message, you misread mine :-P I said they didn't show up in the premade sim bin wich is where downloaded sims end up in the CAS bin :-) Anyway thanks for all the help hoping that the link you provided will fix everything. I saved it to favorites and will look into it tomorrow :-)

I don't see it mentioned above, so sorry if I missed it, but you should never use extracted sims in your new hood, they must be extracted and cloned. If the sim has merely been extracted they come with extra data and you may find they glitch up quickly. So after extracting clone the sim in body shop so that there are two of them and then delete the extracted one keeping the clone. That is the sim you take into CAS.

Ok, hope I get bodyshop working then. How will I know which is the clone since they will look the same. I haven't used bodyshop for över a year and when I did I just created sims I never cloned them

Two options:
The cloned sim will appear at the beginning of the list in Bodyshop, so you can delete the extracted one.
Or you can look at the date created for the files in SavedSims and delete the older one, but if you're doing lots of sims in one go it's a pain to work out which file to delete.

If you're still worried, try changing their clothes or hair slightly so you can tell which is which.

I always find the clone near the front and the extracted sim near the back of body shop.

Yes, I mentioned this and gave a link to a tutorial at pixel-trade. If you know of a better tutorial, I'd love to see the link.

I forgot to mention that one can ignore the bit about packaging the sim, unless one intends to share the sim with other people.
If you are talking about this warning, then you can ignore it, because it doesn't apply to extracted sims.If that's not the message that you were worried about, perhaps a screenshot would help us understand your concerns.
