Re: CAS background wont change.

@iSnoopy2001 @amazesimms  Have you tried clearing your cache after switching the CAS background mods in your Mods folder? You can do this by deleting the localthumbcache.package file from your Sims 4 folder. The game will auto-generate a new localthumbcache.package file the next time you launch it. You'll also want to make sure that any mod you are trying to use, background or otherwise, is current and verified to be compatible with the latest game patch.

Maybe give this a try:
1) Remove all background mods from your Mods folder
2) Delete the localthumbcache.package file from your Sims 4 folder
3) Restart your game to see if the CAS background is back to the default appearance.

If this works, then try adding the new background mod to your Mods folder and see if it is working properly now.

Btw- I delete the localthumbcache.package file from my Mods folder every time I make any changes to my mods folder.

Good luck, I hope this helps :D

I've done all the steps numerous times. I deleted the localthumbcache.package file, cleared the rest of my cache, repaired the game, updated the game, restarted, etc.

This is what my file folder looks like atm:

That is my CAS Background folder in the Mods section. As you can see, there's nothing in it. 

While that was going on, this is what my CAS Background looked like in game:

This is the same CAS Background that I have been trying to delete for so long, why can't I get rid of it?😢😢. I would assume that if there was nothing in my Mods: CAS Background folder, there it would revert back to the default background.....?

Meanwhile, I keep all of my extra CAS Backgrounds, outside the Mods folder, in here:

How would I fix this?

@iSnoopy2001  Is it possible you put this background in a different subfolder?  Try moving your entire Mods folder to the desktop, as as test.  Start a new save to see whether the background is still there.

If it is, please confirm that the Mods folder you moved is the one from the Sims 4 user data folder the game is actually using.  This is easy: just check the last modified date on config.log inside the folder.  Its time and date should match the last time you launched the game, as in, a few minutes before when you opened TS4 to test.

Thank you so much! I just now realized that this entire time, I did in fact have a copy of the background in a Subfolder.

I will update you guys again once it's all clear.

I love the EA Community!

Hi @skyskyxd Welcome to AHQ 🙌

I think you can only load one CAS background mod at a time, so make sure you remove any old background mods before you install a new one. If you have more than one they'll probably conflict with each other. Make sure your new mod is not still compressed in a .zip file or .7z or anything like that. It has to be unzipped into a .package file that goes directly in your Mods folder. Make sure the game did not disable mods and CC in your Game Options during a game patch installation through Origin. Make sure you still have a file called Resource.cfg in your Mods folder.

Another important step when making changes to your Mods folder is to clear your game cache by deleting the localthumbcache.package file from your Sims 4 folder. The game will auto-generate a new cache file the next time you launch it. I delete this file any time I make any change to my mods folder. It's probably over-kill but it only takes a second and it might save me from having to troubleshoot my mods later.

So I have a few questions to help us figure this out in case the above steps didn't solve the problem:
- Are you on PC or Mac?
- Is this the only mod you use or do you have others? (If yes, I don't need to know what they are)
- If you do have other mods, are they still working fine?
- If you put your old CAS background mod back in your Mods folder, does it still work?

It could be that those new CAS Background mods you are trying to use were made obsolete at some point by a game patch. It's fairly common for mods to get broken any time there is a big game-changing patch like the one on June 3rd. Here a link to a great mods tracking site where you can search to see if your mods have been updated or if they are obsolete with no replacements:

https://simsonic.weebly.com/modtracker.html

Just scroll down to where you see "Main Tracker / A - Z" and click on that.

I do have a CAS Background mod in my game that is still working fine so I know for certain that at least some of them should still work after the June 3rd patch. I can't post a link on AHQ but if you go to the Mod The Sims website and search for Old School CAS Room you should be able to find it pretty easily. I love that it has the mirror so I can see the front and the back of a hairstyle at the same time.

Good luck, I hope some of this helps :D If not, please let us know and we can look into trying something else.

I'm just a regular Sims player, I don't work for EA

@skyskyxdOk sorry about that, they track almost 1400 of the more popular mods on that site but it appears that there are some that aren't tracked there. The other thing you can try is go back to the site you found those new backgrounds and see if there are updated versions or any notes about them being compatible or not compatible with the latest game patch. If they are obsolete and the mod creator hasn't made any updates then unfortunately there isn't much you can do about it.

Btw- Can you verify that you don't have any other CAS Background mods anywhere else in your Mods folder? Maybe like a duplicate copy of that old background that still works in your game? Another explanation would be there is some kind of conflict preventing them from working properly. 

Here's another link to a list of broken mods and CC, this one is on the Sims 4 Forum:

I see there are some links on this site for CAS Backgrounds that are updated for the latest game patch. The mod I use can be found at Mod The Sims & you might be able to find something there you like as well.
