There is a workaround that I have tested to remove all of the unwanted character files that the Bon Voyage stealth hood puts into your game. Pescado taught me this in chat the other day, so he gets full credit for this. I am merely the messenger. I have tested this and everything seems to be working fine so far.
1. Back up N0XX folder. Pay attention to how many suburbs you have attached (suburb01, suburb02)
2. Go into the game and enter the hood. The stealth vacation hood will be created. You'll see somewhere around 60 new character files appear (ZOMG!)
3. Exit the game
4. Go into N0XX folder and delete everything except for Suburb0X (the newest, in my case this was suburb03.package). Replace everything with the backup.
When you add an actual vacation subhood it will add another 14 or so characters. I have NOT TESTED this, but in theory it should work. The only changes that you would make would be to NOT replace the LOTS folder from your backup and to NOT delete the vacation0X.package. I am going to test this a bit today, but I cannot guarentee that it won't break your hood. You might want to do the second part on a test hood before actually attempting it on a hood you care about.
Do you actually mean for us to delete everything in our N0XX folder besides Suburb0X? Or just the newest created suburb? Because I was thinking if we delete everything in the N0XX folder (I'm guessing that is the N0XX folder in our "user" folder not C: Drive?) then wouldn't all the Sims, lots, etc also be deleted?
Yes, I admit that I am non-awesome and don't quite understand.
