Last Exception From MCCC
Hi, I was recently having an issue in every new save file I create where when my sims travel to community lots, there are no staff or townies there at all. I thought I fixed the problem after removing a mod I thought to be causing it (Turbolib Simulation Unclogger), and the game worked fine and then it started randomly doing it again. I tested in multiple different new saves and it was still happening. I have been trying to fix this for days and cannot find a fix. I even tested the game with no mods and it was still doing it. I found that I keep getting this LE whenever the problem happens. <?xml version="1.0" ?><root> <BetterExceptions><BEversion>v3.15</BEversion><WasBlank>False</WasBlank><TuningLoadFinished>True</TuningLoadFinished><BadObjectCC>True</BadObjectCC><Advice>This is likely due to bad object CC.

ALL .ts4script files show "corrupted" on Mac ARM - even after full reinstall
After patch 1.121 (Feb 3, 2026), no .ts4script file can load on Mac ARM (Apple Silicon). Error: "Cannot start because the below file appears to be corrupted" Code: [60c399f9:29f00e76:00000000:4b0d852b] System: MacBook Pro M3 Pro, macOS 15.5 Game version: 1.121.361.1220 Tested: - Official S4CL v3.19 .ts4script - FAILS - Minimal 1-command test script - FAILS - Multiple ZIP compression methods - ALL FAIL - Game repair - didn't fix - Full uninstall + reinstall - didn't fix - Deleted localthumbcache.package - didn't fix - Deleted GameVersion.txt - didn't fix - Feb 12 hotfix applied - didn't fix The error code is identical for EVERY .ts4script file, confirming this is a game-level validation bug, not file corruption. Game works fine with an empty Mods folder. No script mods can be used at all on Mac ARM.
Error Msg: 'walkstyle' (value: V) UnavailablePackSafeResourceError)
Hi there, Is there anyone have the same problem as mine in the game? This LE report occurs every time I load my save game with the household that I play the most, but not any new household. Error Message: 'walkstyle' (value: V) (UnavailablePackSafeResourceError), CategoryID: tunable:214 & UI Error Do you have any clues which mods could cause this issue? Thank you.
How do I put back the Penthouse Apartments in Sims 4 City Living?
How do I put back the Fountainview Penthouse Apartments in Sims 4 City Living? The building is gone. I used to have a previous cc lot that was for the Fountainview Penthouse and that made the entire apartment freeze. When I deleted it to add a new cc penthouse, it made the whole building disappear except for the empty lot of the penthouse. The new lot I added to replace it, it made half the penthouse building disappeared. I decided to bulldoze the entire lot to see if the original EA Fountainview Penthouse building (including its lot) would appear. I don't know why I thought that would be a good idea. Now the entire lot for the Fountainview Penthouse is an empty lot. It looks like this: ............. Also, I play the Sims 4 on my Mac Laptop by the way, if that could help for any tips that I can try to fix this if possible.Sims 4 wont start on Mac with any mods in the folder
I haven't played in about 2 months and now when i try open my game it just freezes and never opens. I deleted all the caches, repaired the game, ran app recovery and the only thing that could get my game to start is if i remove all mods. I tried adding them back little by little (i have about 6000!) but i only ended up adding a few 100 and then the game wouldn't start again. Are all my mods just outdated or something, all at the same time? Is there a way to fix this without adding them to the mods folder one at a time, because that's gonna take a while

Hi, I have some strange issues with the game noone else has ;p and one other person who had similar issues said it was caused by mods. I never used any, but then I though I play this game since 2014, might be I used to have some and I dont remember that 🙃 I couldnt find an answer anywhere on the Internets 🤷 So could someone please tell me how to check if I have any mods or CC's installed in my game ? =)
Lot Upload to My Library in Gallery Consistently Times Out
I've been trying to save my households and lots to My Library in the Gallery so I can start a new save with the changes that've come for the new Royalty Pack. I was able to upload all of my households but after uploading two lots, since yesterday, every lot I try to upload times out and fails. I've tried repeatedly for more than a day. My internet connection is strong, so I'm at a loss as to what the problem is, unless it's a server issue on EA's end. I'm using a Mac running Sequoia 15.6.1 and the EA app. My Sims 4 game is fully updated. I do have modded content and custom content in my lots but that hasn't been a problem before for just uploading them the Library. Please assist.Cc not showing up in game
Hey guys, I'm having trouble in the game. My cc in build-and-buy are not showing in game and also some of the clothes. I have cc enable in gameplay and also repaired and restarted my laptop but no luck. I double checked to make sure i put it in the right folder and i did. Please help me!!
Helppp
My sims wont go to work. The option wont even pop up. Anddd a sim outside of the active family (that i had to delete because of this issue) keeps dying over and over again everytime my game freezes. Ive tried to use the better exceptions mod to find whats wrong, but nothing came up. Its Mcc that tells me that theres something wrong but wont tell me what. Just some sort of Drama node. I have cleared my cache, repaired my game, and basically tried everythign. I have only three mods and all of them are up to date. 😭😭
Sims can't sit on chairs or sofas (mod related problem) after update.
Hi! I'm experiencing problem after February 3, 2026 update, where my sims can't sit on the chairs or sofas, only on beds and bar chairs. My Last Exception is telling me (AttributeError: 'NoneType' object has no attribute 'expected_kwargs') and last exception assistant tells me "outdated tunable resource error and outdated tunable resource (interaction) requires removing" how I can find the mod causing this, I have tested probably all my biggest mods and have updated most of them aswell and also tested some smaller mods, but the problem is still there. (All of these are tested one by one or updated and are not causing the problem.)
Last Exception Report: vehicle_liabilities.py
Hey guys, I've been having this issue since the pack released, where everytime a sim rides a kayak it produces a last exception report that reads: Last Module Called: vehicle_liabilities.py Last Function Called: get_start_node_index_for_path Error message: Exception in prepare_gen for super interaction. (AttributeError: 'NoneType' object has no attribute 'can_transition_over_node'), CategoryID: vehicle_liabilities:30 After that, the game runs for a while and then crashes. I'm not really sure if it's a mod related issue or just a bug, since I haven't seen many people with the same problem.
Mailboxes interfering with Build Mode
I’m having a problem where every time I try to put down a lot or move a saved a lot from my gallery. An error message pops up “ this item can’t be deleted” or item cannot be removed. I went through every item on my lot and it seems to be the mailbox. This is a problem because you can’t usually delete the mailbox now without a mod first and if you try to put down a lot before you delete the mailbox, you will be stuck in a white never-ending loading screen. I had to restart my game three times in order to find the problem So my two problems are the fact that I can’t delete the mailbox, and if the mailbox isn’t deleted, I can’t put down a lot from the gallery or even my own library without deleting the mailbox first otherwise you will get stuck in and never ending loading screen.
Young Ghosts Return Thread 2.0
I had to remake this thread since 1 edit to correct stuff since It was way outdated got it falsely removed by auto mod and wanted to get the main page up to date. So I have to remake it. I'm going to use the info from mod the sims to make it easier on myself. This mod brings back the old days where you can cheat Younger sims to be ghosts. With the Life and death update. The sims team restricted on which ages can be which type of Ghosts. Which made Toddler, Infants, adult pets and baby pets to no longer be ghosts. This mod allows the old days again so they can be ghosts again. There are side effects like stretching from young meteor ghosts doing the death animation. Toddlers walking slow but other then that it works well. Toddlers who have the laughter trait can make people playful like adult. This will also fix certain features like The premade Ghost Dog Captain Whittaker and fix the wishing well issues when you get a Ghost Child from there. I made this mod personally but I had people ask me from places to share it. Pets can only be Old age for reasons. I will say this. Bugs. I don't want to get this one removed and that might have been the reason. It brings the old days. They still can't die but you add the ghost traits with Cheats like the trait equip cheat. MCCC or UI cheats. The traits were enabled for them so all ghost types in the normal game are enabled for them but not death. You just have to add the traits to them with cheats like how it was before Life and death patch. If you use Young Ghosts Return and want to upload them to the Gallery or somewhere. Make sure to include this in the description. #YoungGhostsReturn That way. People will know the mod used in the upload with young ghosts and why it's marked as custom content. It will help a lot and clear things up. This thread you will see updates and the status of the mod in the comments.black stripes on sim
