This problem has been here for a while, but i just ignored it.
ALL of my neighborhoods apart from Veronaville and Riverblossom Hills has dissapeared, i have deleted the NeighborhoodManager before to try and fix it, but all it has done is created a new one and my neighborhoods are still gone. All of the files for the missing neighborhoods are still there, I removed my CC to see if that worked, nothing. I didn't do anything to make the files delete, so I don't know the main reason of my problem..

If you need any more information then ask me, please.

Do you have any downloaded hoods in your game?

If you do then they may have the same internal numbers which will make both not show up at all, if you have more than 1 with the same internal hood number then all with conflicts will not show up in game.

Disappearing hoods is normally the final death groan of corrupted hoods.

Did you delete any sims from the family bin?
Did you place occupied lots (including with graves) into the occupied bin?
Did you move sims between hoods?
Did you use the delete all characters cheat?
Did you install an occupied lot? (not made by maxis)
Did you remove NPC creating mods. For example a muli PT mod, an item that moves around a lot such as the surfing mod, roller coaster or animals?

No, I have never downloaded any custom lots, I haven't done anything else of what you said too.

Well the next possibility is they are pre-made hoods (made by maxis) and they have simply run their course. They all come already corrupted and need their life extended by regular mop ups with Hood Checker. Have you been using Hood Checker on them? You could run Hood Checker on any backups that you have, that might get them back for at least a while.

No I haven't, i'll go try that now.


Edit: I just tried it, the files for the missing neighborhoods were blank, and i couldnt click them inside of Hoodchecker, but when I went back to check my neighborhood files outside of it, the files were still there.. I'm guessing they're corrupted?

And I don't care about the sims in the saves, I just want the worlds back without corrupting my current two worlds that I have.

Worlds? Do you mean hoods? Worlds are a Sims 3 thing. Each hood is separate. You can get the pre-made hoods back from the installation files but they will be unplayed vanilla condition. Or you can download cleaned up versions.

Yeah sorry i mean hoods, I'm a Sims 3 player. I'll go get the pre-made hoods now.


update: I found this post http://modthesims.info/wiki.php?tit...t_Neighborhoods and followed it, and it worked! Thank you for your help.

That's it. I would use hood checker on it first then make a backup. Then continue to use it often.
