When a new SimPE is out I'll try to make an actual clean stealth neighbourhood and vacationhood.

And the 'stealth' people? They're added by the stealth neighbourhood. Look in the V001 folder in the neighbourhood templates. It's there, and will add itself whether you like it or not. They're an EAxis screwup.

EDIT:
Upon further testing, using SimPE 0.62 (yep, the Seasons one), and opening the .neighbourhood files AFTER the characters are gone, it's actually editable. It's just very finicky and yells at me. But at least it works.

EDIT Mk. 2:
And created a worse BFBVFS. This time when adding the files. Good thing I made backups.

When I did it my idiotic way (deleting the .package files that the sims were contained in...) the locals to the region DID have their actual vacation-ish skills. The slap dance, the chest pound in three lakes, specifically. Just their clothing was wrong, and the hairstyle.

So, if the locals get deleted they don't regen with correct outfits? How about the behaviors... the gestures of the region and such?

I haven't played a ton yet, I've been too busy building my own vacation locales, but it seems like I'd see 1-2 locals/lot with the rest being regular tourists without special outfits... is it possible your game just hasn't seen fit to generate locals yet so you're only seeing tourists, hence the randomness of dress, or have you confirmed that they're actually locals?

Finally, count yourself lucky that SimPe even lets you get as far as seeing that they don't have pics - on both my comps SimPe barfs out about a gazillion errors (Warning: Sim Found Twice type of stuff). If I get through all the errors there's a bunch of gobblygook - the BV sims don't seem to register (empty family infos, etc.) and my playable families show unknown members and stuff. I'm hoping it's not truly that screwed up and that SimPe is just not reading it right. Sigh, I tried to sign up for the QA about six weeks ago but never got a response... wish I had it now, I think there's a version out there for testing.

And just for the hell of it, fuck EA for screwing up my neighborhood. I just know I'm going to BFBVFS trying to get rid of the crappy characters I don't want.

I thought the correct clothes were available from CAS or bodyshop.

I made a townie out of a MATY sim, and gave him a job just like you.  When he fell in love with a playable and moved in, he had an entirely different job than what I set him up with.

So I'd say you're probably wasting your time as far as jobs.  I think they keep the skills you set, though -- I don't think those reset.

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.

I just tried to fiend tge mod Customizing Christianlov's Custom Skintones Selector but got the message:

Reason: bye
Does you know why? Or other ways to get the mod?

This is just the hair from Andy and Lucas, nothing else. Also fixed it so that it no longer resets to the default hair when switching colors.

I don't think it's updated for Seasons yet, if it will or needs to be.

It was an outdated version of harderjobs.

These aren't showing up in my game for some reason.  I downloaded the full set vilia provided and deleted the CAS thumbnails file (though it isn't just the thumbnail that's not working, it's the whole template).  I tried taking them out of a subfolder and putting them directly in the downloads folder, but to no avail.  When I go into CAS, I still have the fugly maxis templates.  Anyone have any ideas?

Or adjust the risky pregnancy odds. I couldn't make my sim Try For Baby with a townie, so I upped the risky odds to 67%. Actually she still hasn't tried for baby since I installed seasons. I moved him in tonight so we'll see how it goes.

Make townies, and then use the Teleporter Shrub to turn them into Downtownies.
