'System Error' when placing lot

I got the same problem. On ps5, no mods, a bunch of EPs, using 64x64 lot in Chestnut Ridge. Not able to place a lot from gallery. Saved to library and tried again, still no. 

Yes mine was on a 64 x 64 too but in San sequoia 😭😭😭 haven’t played since, not going to until this gets fixed cause I’m not going to waste my time building for nothing  

I spent months (no cap) building a 64x64 apartment. Uploaded it to the gallery (after that got fixed) and now I can’t place it on any other lot it says system error 🙃. I made it on a discard file to start a new save file cause my main/ only save became too buggy and broken. Please fix this build. I’m not building it from scratch, it took me months. 
I’ve reported this, waiting for a response on how to share a save file on ps5. I have 90% of the packs. (Have also brought second copies for mac) I’ve spent around £2500 on this game. Please fix this. Don’t want to play again until this is fixed cause I’m not wasting another 7 months trying to recreate this same build. I beg.

How do I upload on ps5?

Exactly same thing happening to me! Can't place any lots i built and saved before... i tried diffrent locations and every time same system error... what are we paying for.. they make new packs but doesnt fix the game.. i struggle to enjoy the game recently.. constantly struggling with some bugs..

I play on Windows PC, have mods/cc, the lot is from one of my saves and I am trying to save it because I made paintings and placed them in a small room but when I download just the room the paintings are blank so I saved the lot and tried to place it onto another 40x30 lot and I get this system error? 

I built a home from the new Adventure Awaits pack on the Jellyfish Jubilee lot. I saved it to my gallery because I thought I wanted to rebuild. When I went to place the house back onto the same lot from the gallery, it won't allow me to place it and says "error". I've used bb.moveobjects on code, even bb.enablefreebuild and it still won't work. I even tried placing the gallery house onto another lot and it won't work.

Hi ellynbang​ 

there's a few similar thread for this so could you post the full error you're getting ?

Just error ? Could you post a screenshot ?

This suddenly started happening to me a couple of weeks ago and it's very frustrating. It happens across saves, whether I have cc on or not. I've done all the suggested fixes and nothing works. The game will also tell me "content not installed" when I'm trying to place the lot, even though I literally just saved the lot and am trying to place it elsewhere without having closed the game. I hope this is one of the things they're going to fix in the bug fix update, because if not, the game is as good as unplayable for me.
