I cannot place objects in Build/Buy

@bigpuppydogeyes  If you move your Mods folder to the desktop and delete localthumbcache.package, is the problem still present?  If it's gone, what happens when you add back a single mod?

The problem still is present after I tried your method. As I put all my mods and cc back one by one it still would not let me use the bb mode. I trying for every last option before I remove everything and Reinstall.

@bigpuppydogeyes  Just checking, but after moving the entire Mods folder to the desktop and deleting localthumbcache, was the problem still present before you added back any mods?  Did you see any evidence that your mods were still present in your game?  It's possible the game is reading a different user folder than the one from which you removed your mods, in which case we need to find that folder.

If you are in fact looking at the correct folder, try moving it, as in, the entire Sims 4 folder, to the desktop.  Repair the game in Origin: open your game library, right-click on the Sims 4 icon, and select Repair.  Then launch the game; a clean Sims 4 folder will spawn with no content.  Don't add anything to it until you've tested.

There was no evidence of mods in my game, and when the mods were gone it worked. But I’ll try this other method when I wake up because it is early in the morning for me

I have just loaded my game for the first time since the March 2021 update. When I go into build/buy mode, all the build/buy options are there however I cannot click on them to place them. It allows me to change the swatch of the item, but when I click the item it does not give me that item on my cursor to place. I have restarted SIMS 4 and my Mac 4 times now and it's still not working... help!

I have the exact same issue. I will check all my sliders first because they are usually the issue...

I fixed it! I had the expandable catalogue mod, which I guessed might have been the problem. I took it out of my Mods folder and now the build/buy catalogue magically works again... Had to restore my previous save though.

I tried to get rid of mods and it worked but I want the mods so what do I do to fix this I tried putting it back in and the same thing happened again 

Sims4 CAS items missing !!

If you see the photo, there are some items missing and not only the custom items but also the default items too...

Has anyone been through this problem? pls help !!
