I have broken the spire tower when I was trying to renovate it
Now I cannot save any changes that I'm trying to make

Everything required is present? The elevator, the trash chute , etc.? If you lost the Spire Apartment shell you can use LunarBritney's Unlocked Apartment Shells

I just saved this mod for future use in case this bug happens to me. Thank you!
The bug I have right now is with the FountainView Penthouse that I bulldozed and now I can't fix it!
I've tried to use the shell from the "Unlocked Apartment Shells" mod by @LunarBritney but when I take the mod out, the shell disappears.

Is it possible to have a shell just like this one? That keeps after deleting the mod?

Ty!

OK, I'll make the same for other shells asap, hope this will help)

You are so kind! <3 <3 <3
It would help me a lot and not just me but a lot of other people with the same issue as well!
It's sad that the answer EA is giving to fix this issue is to start a new save

Done) I've read that the issue still persists on 1.105, but I could not replicate it in any way (IDK why), nevertheless keep this kit closer to your mods folder)

You are an angel!!
Thank you so much!

And yes the issue still persists until today.
I've been commenting on EA Anwers post for a long time, reporting the issue and bringing back the discussion but EA doesn't seen to care tho.

I'm having problems getting this to work. I was trying to convert the Stargazer Lounge in the Uptown penthouse into an actual residential penthouse. When I place the shell into position, it sinks in and the top of it is flush with the ground level. I tried putting down a floor and then raising the foundation to it's maximum height but it doesn't lift it high enough. The base is still deep underground and the apartment is floating in mid air.

Couldn't you attach some screenshots of this issue? Looks weird, this lot does NOT allow to add any foundation as the lot level is hard-coded. Try to raise the shell with T.O.O.L. temporary

Here are the images

And the apartment itself is above, right? Do you have pool or basement floors on it? I suggest that the shell sticks to the bottom of them. Or this is a clean lot? That's really weird, I can not even replicate this issue, the game does not allow me to do this (as intended).

The lot has been bulldozed several times now. I'll just give up on this one. It's only 1 lot out of many. Thanks for getting back to me.

Couldn't you describe step by step what you've been doing with this lot? (This will help me a lot to investigate the core of that issue. That seems similar to how the attractor point for LoveGuru disappeared once and never got back in my save, seen about 20 sims with this special trait but none of them is selected to this role because of the missing attractor point triggering their role state (....and lots of festival objects not despawning properly and floating high in the sky layering multiple times...(bloated my save file up to 526 Mb as they are counted as objects to be saved) this is through years and never been fixed, sadly. You might see tons of vendors doing nothing, because the stall is light-years away but they were ordered to spawn))) San Myshuno is not builder-friendly....want to place the restaurant or anything else instead of default lot types? prepare for pain.....(((

You can use my trick of buildind the high-rises (do NOT bulldoze ever!) 1. Build a room of any size but leave 3-4 tiles for further purposes. 2. Stretch the foundation to max. 3. Build a one-tile wall one tile from the foudation and the another one,then move it into the gap. 3. Stretch this wall up, so it will stretch up the foundation 4. Repeat as many times as needed)
