Does it change a child's astrological sign if the parents teach them to be clean/sloppy, lazy/active etc?

It does not. Unless deliberately and specifically changed with an editing tool, the star sign is for life. The genetic personality will also be retained (you can see it in SimPE) and whatever DNA recombination does with the personality points will be done with the genetic personality.

Question for SimPE boffins (Gummi you may know this). I've edited an object package and solely changed the object, but lots with the object already on them don't pick up the change even when deleting cache files. Is there a way to have them 'refresh' so you don't need to replace each one manually with the new version? To clarify this is the same package, not a clone.

Object creating is not my strong side, I'm afraid. I have not heard or read anything on how to make changes apply, other than re-placing the object, so that's the only method I know of. Try the object modding section, there are some very talented creators who read those that might be able to help (Create-button at the top of page -> Sims 2 Creating -> Object Creation)

Yeah or I may ask Frac at PBK. He's helped me before on object creation.

Can a married sim move out without being divorced?

I have two playables (Guy and Constant) who were dating the same townie (Marie-Ange) without me to notice. Later Guy married Marie-Ange but soon after her marriage Marie-Ange showed up at Constant's house. Constant and she now have an affair. When I played her household, her wants panel is full of wants for Constant so she'll leave her husband. I want her to leave him (her husband) without a word. They will sort things out later.

Yes. In Drama Acres, Trisha Traveller engineered a caught-cheating event with Julien Cooke and then moved out voluntarily. Later she had to invite Trent over in order to divorce him.

Thanks Peni.

Another one.
I have a sim who reach the top of the law enforcement career. Is it safe to use a default replacement career if a sim already is in this career?

If you go with the warning CC career creators add to their downloads, that you should make sure no sims is using that cc one before unistalling it...I'd say it is not safe to do. Or maybe I am mistaken sims3 with sims2...

You can uninstall it, just make sure the Sim is at home (or have him find another career before you do).

Hum, it seems I wasn't clear enough. In fact I want to install that default career in my game.

You were clear.
I was just thinking that if it is not advised to mess with carrers if sims are using them, ...replacing them with default might not be a good idea either. I would still wait until my sim quit it. Or when that sim is not at work like JustPetro said, at the very least.

Either back up your game and try, or do as Rosebine said and quit first. I'd use SimPE, that way it does not generate any memories, both removing and giving it back after

Sorry, @Essa, you were clear, I was half asleep I'd still go with being sure the Sim is at home, I think.

Thank you all.
The sim is currently at home. I'll make a back-up and see the result.

bringing home classmates/co-workers, can those be lot-specific and/or sim-specific? "lot-specific" meaning only certain lots getting classmates/co-workers, "sim-specific" meaning only certain sims bringing classmates/co-workers.

Can you sell individual bowls of grandma's comfort soup? What about individual glasses of juice?

The individual servings of soup, I don't know; for what it's worth, you can't normally sell the serving bowls of it---I have tried with the serving bowls, and you get the message that the object cannot be set for sale. (Striking out because gummilutt's post below indicates that perhaps I have some sort of glitch that causes this.)

(From what I have seen) the multiple-servings soup bowl is distinct from other prepared food platters in inventory, too, probably partly because of that.

The juice, I know you can't in the sense that there's no way to take a juice glass out of a sim's hand; they make it and drink it. With this mod suite , you can put trays of juice on sale (and that mod suite also fixes juice trays in some other cool ways; I use it and love it). And supposedly, this mod allows you to sell juice out of the juicer at an OFB or unowned business. At an OFB business, sounds like sims don't buy the juice autonomously, but you can always visit the lot (owned or unowned) and buy that way.

I have not tried cedrigo's mod, because it conflicts (as stated by cedrigo) with Jfade's juicer tweaks posted on MATY, which I use and prefer to a similar but less-solid version (by another modder) that can be found here on MTS.

You could try this mod. You'll get the chance to say yes or no at least.

Pretty sure you had some other problem going on nat. Comfort soup can be set for sale just as any other dish, both serving bowls and individual bowls.

Here they are, set on sale at my hood's takeout restaurant.

Oh my goodness, thank you so much, @gummilutt! Really appreciate the heads-up. It's true, I only ever tried it the one time. And, lol, now I've built an entire subset of my hood's economy around the premise that the soup cannot be sold in an owned business but must be bartered for privately...so that's not a bad thing, but I am delighted to know for the future. I appreciate the correction.

Editing to add: Edited my earlier post to point to your post as evidence that I was wrong about the matter.

Here's something I keep wondering about, now that I play the UC, and that I've never been able to get a good answer to.

Did one of the later expansion packs significantly change how attractive autonomous book reading is to sims? Because in my old game that had expansion packs through OFB, uni students who were Serious would regularly do it when they were low on fun. Some other sims too, but mostly I noticed it at Uni.

I've seen a sim maybe once autonomously read a book for fun in my UC game. This mod 's existence seems to imply that it was something done to books in Freetime. But of course it's sort of indirect evidence.

Can anyone say whether their later-expansion-pack games regularly feature sims who read for pleasure, autonomously? Or have you noticed too that they don't so much? Bonus points if you have noticed or remember anything similar (or in contrast) to what I remember, that my sims through EP3 did do it much more.

(Er, sorry, I guess I just double-posted. But since they're two very different topics, I'll leave it that way for now---someone please let me know if I should combine the two.)

Are you sure they that they weren't studying class research?

Oh, very, very sure. I'm steadily breaking myself of the habit of micromanaging my sims, but back then I was only taking baby steps. And one of them was that at uni, I would let them handle their own fun and social needs, directing them for everything else. I didn't actually allow any autonomous classwork---they had to have rolled a want. So if they went to get a book, I'd always look to see what they were doing with it and cancel the interaction if they were trying to study without a want. But they usually were pretty desperate for fun if I was giving them free rein like that, so it would have been surprising to me if they were trying to take care of any other need. Not impossible, just surprising.

More important, I also remember being a bit irked and often consciously staying my hand when they went to read for pleasure, because I knew that book reading would not raise their tanked Fun as fast as other alternatives. But since that was what they were choosing to do, I let them---so again, I have good reason to be sure that they were reading autonomously, because I had to deliberately remind myself to allow them this choice.

And look at this mod . Surely that would not be needed if they could not autonomously read, right?

I'm not trying to be argumentative. It really puzzles me, and I wish I could figure it out. Why do we have both mods to stop them doing it and mods to allow them to do it? Doesn't that seem strange?
