Even tho you said you removed your downloads folder, stray hacks can come in thru dowloaded lots and/or collections folder.  Try backing up the entire Sims2 Folder and then backup that Neighborhood, remove the Sims2 folder and let the game spawn a new one.  Put that Neighbood back in, go in and then see if the option is there.  If it is, then you've got a stray hack conflict hiding somewhere. 

   Emma, if you have AL, the fix from Paladin is under his AL Fixes Category.  "Harvested Plants Disappear Promptly" 

   Niether ISM nor ISA have been working for me at all tonight, ever since #grah went kaplooie.

   I can't believe it, a lowly Peasant helping out a Senator.  Checking out the RAR file, all NH decorations seem to be included, shipwrecks/sand-Rock spit/Henges.
   Edit, 2 different RAR files, me bad.

   Taking care of his many 'babbies' is keeping him very busy.  It's either that or he's old and has a long beard.   

   No idea if this applies in your situation, but this was posted at TS2 forum.
"You can't place rugs using the new cheat or it will bork the texture, so make sure you are not using the "quartertileplacement" cheat or the "snapobjectstogrid" cheat."

   

   The only time i've ever tried accepting an outing invitation, a total of 10 different townie's got out of the taxi when they arrived at the bowling alley.  I blame Neko for that, as i had just finished reading one of her Clown Car chapters.

   Technically, i didn't break the rules when i downloaded those 'special' hacks.  I had my Fat Gwilly People mask on.

   I've seen one other thread posted at another site about the double-Uber exploit.  I haven't tried it myself (i'm STILL working on avoiding game crashes).

You should do this from medium to high altitude for best results. Fire an Uber Turret at the planet's surface and then, RIGHT as it begins deploying, minimize (This is seriously crucial. If you minimize too soon, it won't deploy and you won't get it, if you minimize too late, you won't get it. You must minimize as SOON as you see the turret begin to unfold). Wait for about the time it takes for the Uber Turret to construct and begin flying about, then bring the game back up. Once the Uber Turret is finished recharging, it should glow as if you don't have one yet. Deploy the second one (DO NOT leave the planet before you do this) and you will have 2 Uber Turrets flying around on the planet.

   Further on down, the OP suggests that the Spice Storage Module must NOT be placed before trying this exploit.

   I just finished my first run from cell to space, and i noticed the mini-map at Civ stage is NOT the same as the planet-mini-map at Space stage.  The Civ mini-map (in my game) showed slightly less surface area and omitted showing 1 city entirely, tho i managed to find it by scrolling around in the big map.  At Space stage, the mini-map showed the whole area.
   

   I'm all for giving credit (and blame) where due.  It isn't a CEP issue.  It was a CEP (thanks prior to FatD) fix of an EAxis issue.

   Ah, i wondered why this looked so familiar, i arr'ed this a while back.  Available from TPB.

   I don't think it isr, as newly transitioned kids always roll up the lemonade stand, then roll up another toy (besides electronics and game=for me anyway).

    I also was a faithful user of Liz's noPrivacy mod until i installed AL.  At that point i wasn't sure if it was not playing nice with my other mods or not, so i felt safer letting it go (even tho i wept over losing it).  I appreciate getting an updated version based on it.

   This begs the question, have they made any changes to those 'special' NPC's?  Grimey, Hula Girls, Mrs. C, taxi/car pool drivers, Remote Control cars, etc, etc?

Pescado made a comment on #grah about putting all those objects on the lot before converting to apt.  That way each household can use them.  Not sure if the Lot Sync Timer is 'sharable', but it should be.  They'd be the same as my community gardens (harvestable plants only show up for the household who actually plants it, so one family could have all tomatoes, the next could have all Egg Plants, on the same garden plot).

   Well, you did better by googling, but you didn't search the right site.  I managed to find this thread here at MATY explaining exactly how to fix the Spawn - Memory Manager glitch uning the Lot Debugger.
http://www.moreawesomethanyou.com/smf/index.php/topic,4117.msg116366.html#msg116366
   Basically, you will need to have the game in debug mode, click on the Lot Debugger and force errors on all off-world.  Reset everything UNTIL you see the Memory Manager - Old, then delete all of those you see. 

(Edit:  Hur, that'll teach me to not preview my post and then go to bed.  Points and Laughs at himself while poking myself with sharp, pointy sticks.)  Thanks Simsample

   Easily.  Collections folder, Config, LotCatalog, Paintings, SC4Terrains, Teleport.  Or, a hack/mod could create it's own folder (ex: zCEP-EXTRA).  I just recently installed Numenor's Scriptorium, and it installed some invisible folders (which i knew it would ahead of time).  The point being, it's way too easy to download stuff with extra features.

   Okay, scratch one theory.  On to my second shot-in-the-dark.

   CC objects.  I've had CC objects in my game, that had strange interactions showing up.  Turned out the creator had missed removing/fixing something (and it was no big deal you-know-who, can't test for every EP/SP config).  Do those odd interactions still show up when running those lots in a completely clean game?  If no, then either a hack conflict/bad CC needs to be tracked down.

   I'm the most un-awesome person here, but...   Could there be testing-objects still on your lots that you had spawned?  For instance, there's Tombstone of L&D, Rodney's (Death or Clothes or something) plus others.  Would leaving them on a lot AFTER turning off testingcheats cause those problems?

   During the L&P phase, i remember a tidbit of information that was mentioned. 
Quote: "Different living experiences based on the surrounding communities impacted by rent and noise"   http://www.simprograms.com/?p=429
   Yet this wasn't mentioned in either of the chats nor since release.  It makes me wonder if they left code-remnants (GASP!) in the game relating to what type/quality of lots surround the apt lot?
   Questions arising that need answers: (My gaming comp is on the fritz, so unable to play me sims right now).
   Would leaving the custom lot as residential until after placement and then making it an apt building alleviate the dreaded borkness?
   Do surrounding lots actually have an effect on the rent prices?
   Could this be the reason why occupied apt lots can not be moved?
   Would changing surrounding lots after setting up occupied apt lots, bork those apt lots?

  Hello?  <taps the microphone>  Anyone here?

   Also, while in-game, go to Settings - Online Settings, and make sure  'Prompt at Startup' is unchecked.  If it's asking you to register, then that must be checked.

   That's another old bug.  Have you influenced those YA's to do someone else's term papers?  Either at that lot or at another lot?  Even if they do someone else's term paper, the game thinks they've done their own.  That's why i only use townies to influence.

   So far, the only weirdness I've seen with playable-neighbor kids, one non-controlled playable kid missed the bus one day (the bus showed up, my controlled teen made it, the kid had gone the previous day).  Shortly after 9 AM, the kid came bebopping out of his trailer and proceeded to play to his heart's content.  At 2 PM, i get the warning that the kid missed school and lost a grade.  At that point, his mother (again, non-controlled neighbor) fulfilled a fear of 'kid getting a bad grade and lost points.  Shortly afterwards, she came into the controlled trailer and had a nervous breakdown.  She went thru the whole spiel (reaction to the doctor, tho the doctor wasn't visible).  I hadn't played them since moving in, so they had no buffer asperation.
   It worried me so much, i grabbed the kid and had him do some homework (via Inge's homework table). Once i released him, he would walk out of his trailer, go do 1 action, then immediately head back to his trailer.  30 mins later, he'd do it again.  Rinse/repeat.  I deleted him (move_objects on), then he walked back onto the lot, perfectly normal.  The next morning, he caught the bus with no problem.
