Two technical questions regarding sims' age and the Science Center

1 - The only way to do this entirely safely is to create a new sim who is a teen but is based on a CAS saved sim made out of the YA one. That's of course not the same thing as aging a sim down, it will be an entirely new sim who looks like the original but with no accumulated skills or experiences and no relationships to anyone else in the game until such relationships are established in other ways. But the game really doesn't like it when sims are aged down below the YA stage, all kinds of glitches can arise if you force this to happen through CAS for example on an existing older sim.

2 - Maybe I've just been really fortunate all this time, though I haven't played in SV for many years, but I've never had any trouble with any of the science centers I've placed and gone on to use for the location of a custom private school by way of the Careers School mod. Even science center rabbithole rugs placed in the basement of an overly simple shack looking structure have worked out fine, provided proper access is given to the rabbithole rug and there is enough space around it for sims to get in and out as required.

If you don't want to go through the steps of designing your own, perhaps try just about any of the pre-made structures from other worlds as available through Build/Buy?

1- You can activate testingcheatsenabled true, then shift click on your sim and choose Edit in CAS. From there you can age down your sim. After that, remember to disable the testing cheats (testingcheatsenabled false).

I did that once to age down to teen one human turned imaginary friend who had aged-up to adult before his “owner”. I had no problems in that save and he aged-up again normally, had kids, jobs, no problem. Except that he had a random boarding school diploma already, but I was able to enroll him in the school again by sending him there, though he didn’t get a second high school diploma later.

To avoid problems, just make sure your YA is not employed in a job that teens can’t have and is not pregnant. And backup your save as problems may happen as igazor said.

Thank you, Igazor and Keiomestre.

1. I take it I could try and age down the sim, but it's risky. As I'm talking about several sims, I should probably drop the thought.

2, The original SV science center has always had issues for me. When two sims arrive at exactly the same time - for example with the same carpool vehicle, one of them gets placed in that hedge. The only possibility to solve that is a full reset of the sim. If it's one going to school, his homework will be gone then. Deleting the hedge was an easy solution though.

As far as I have seen on the NRAAS board, I'm not the only one with the issues with the SV science center and the NRAAS careers mod. I followed the suggested approach to try the last test version of the mod, which made the situation slightly better. The automatic push of students still fails (if I do a manual one before the automatic one kicks in, that one fails too), but I can at least do a manual push after the automatic one gets canceled at 9:30 am (this didn't work without the test version). That worked for me, but it doesn't work for the townie students the mod sends there; they will fail school because they will never be able to get there.

I guess I have to look up the commands that show me the science centers of other worlds. Those seem not to be visible by default.

The EA rabbithole buildings that are available for us to place in any world are in Build/Buy, when invoked through Edit Town, under Community Objects. Are they not showing up there alongside of the rest of them? Technically we don't have to be in Edit Town, we can get into Build/Buy on community lots with testingcheatsenabled true and a shift-click on the ground, but for some reason when entire buildings are involved it always seems more natural (to me) to use the Edit Town route. Plus the actively played household won't be charged that way for any landscaping or other items one might want to add to the lot after the new building is placed.

Thanks again! I will try and see whether I get this right.

Okay, after the new Windows 10 update got fixed with another update, Sims3 starts again.

I looked at the Build/Buy options, and do I get this right that you refer to putting a new building shell onto the existing lot? Is the actual function of the building (science lab plus whatever school function NRAAS career adds) tied to the building shell? I always thought it was the lot itself. Sorry if that sounds stupid, but I haven't really done anything with community lots in this game yet, except a few cosmetic changes.

When a community lot contains one or more rabbitholes, the purpose of the lot becomes driven by the rabbithole(s) that are on it and not so much by the community lot type. The usual choices for a school or career building lot would be Visitors Allowed (if you don't mind sims hanging around who are not there strictly to use the rabbithole, perhaps your school has a playground off to the side for example) and No Visitors Allowed (if you want sims to use the rabbithole and then leave after their business inside whether it be working, going to school, or something else has concluded). All of the other community lot types are really for open lots.

So, in the end, it doesn't really matter if you re-use the existing lot that a science center is on, replace it (if Edit Town lets you), or use a different lot entirely.

Ah, thanks again! I actually remembered now that the SV town center contains one lot with three functional buildings on it, one of them functioning as school with the mod in question. All of the options other than the science center work correctly in my game.

There's still much I don't know about this game. Sometimes it surprises me with having a lot on a lot and a building on it (three bulldozing steps). Maybe, that's where the beautiful vista function is tied to.

In one of my wilder experiments I had a heap of instant babies and quickly aged them up to Young Adult - then used something (I don't recall what now) to age them back down to toddlers so they could learn some skills. It was an interesting mess. Lots of really broken sims resulted but I did, after a lot of time and effort, manage to get them appear to be function as toddlers. Then I abandoned the game and have no idea where to find the save now.

These days, whenever I'm slightly tempted to age a sim down below Young Adult, I have a little shudder as I recall the previous mess I had and decide I don't really need to do that just now.

Heh, that sounds "exciting"! Thanks for sharing.
