Broken/Updated Mods and CC List Archive The Broken/Updated Mods and CC lists cover newly reported broken mods/CC, mods that are obsolete because of game updates (usually, these are bugfix mods), updates to mods/CC, creators whose mods are cleared as compatible with a game update, and new bugfix mods. The current list (pinned in this forum) also includes a selected list of previously broken mods — that is, still broken. Each list also includes creator news, such as creators retiring from modding, on temporary absence, adopting others’ mods, doing a major site move or overhaul, or passed away. A new Broken/Updated Mods topic is started at most game updates because most game updates change enough code to prompt many new necessary updates or to send creators to the files to check if their mods are still compatible. The topic will be regularly updated all the way up until the next one starts. You can subscribe for notificatiosn so you know when there are new additions, or bookmark it to check back regularly. Major patches with many updated mods are emphasized below. Some mods are updated often; some mods rarely are. If you have a problem with a particular pack or major feature, it can sometimes be helpful to go back to the thread for when that pack or feature was new. However, a mod updated two patches ago could be broken now. Links for Broken/Updated lists for patches before 1.101 go to the “vanilla” Sims Forums. If you have questions about anything there, please bring those questions back here, to AHQ. Lists before the Werewolves pack are not included here, but most of you shouldn’t be going back that far anyway. If you have older mods that don’t have updates available or aren’t recently cleared as compatible, do a 50-50 on your Mods folder.

In This Post Malicious Script Mods and Malware Mod Access: Folders/Mods Missing or Corrupted Loading, Saving, and Crashing Errors and Last Exceptions (LEs) Malicious Script Mods and Malware Beginning as early as mid-January 2024, we began seeing Sims 4 script mods with malicious executable .exe code hidden in them. Shortly after that, we saw a case of fake mod updates being used to spread malware indirectly. Please see Malicous Script Mods and Malware for what you need to know about this. See How to Use Mods and CC for tips on safe sourcing of mods and CC. Mod Access Problems Unable to locate Mods folder common causes: looking in the wrong folder, multiple Mods folders (often caused by OneDrive), folder was deleted or dragged out for testing and you need to relaunch the game to create a new one. For info on your Mods folder, see How to Use Mods and CC. For support, please head to Sims 4 PC Tech Support or Sims 4 Mac Tech Support. Mods/CC not appearing in game common causes: mods/CC not re-enabled antivirus interfering with re-enabling mods/CC multiple Mods folders —often caused by OneDrive mods not installed correctly — wrong folder, too many folders deep, missing parts of the mod or other required mods, etc. corrupted resource.cfg — delete it so the game makes a new one default replacement mods/CC and translations not being loaded early enough folder called "Mods" inside the Mods folder corrupted GameVersion.txt file right after a game update — delete it so the game makes a new one. File corruption One possible cause is changing your folder contents while the game is running. Delete the corrupted files and obtain new versions.

Parts of the last exception near this text will give you an idea which file is your issue. Check with the creator for mod updates or other instructions, typically about new requirements. degree_tracker – this is sometimes mod-related and sometimes a game issue but usually caused by cheats; the linked thread includes instructions on how to use MC Command Center to fix Sims producing this error if it is caused by mods or cheats developmental_milestone_tracker – can indicate that a CC object tied to a Milestone was removed: either put the object back in the build or use the bugfix mod Miletone Fixes by Lumpinou drama_schedule_service failed, DramaNodeScoringBucket not 97 – causes include having removed freelance custom careers or phone invitation mods; this error rcan generally be fixed with a “Save As” fishing_location_component.py – caused by having a mod for a pack you don’t own, including files for Somik & Severinka - Realistic Cooking Mod (EA Override files), Srsly's EA Adjustments (New Prices version) guid64 – known causes include outdated career or university mods HasTunableReference - a script mod that needs updating for the 1.116 patch (July 1, 2025); this did not affect all script mods, but do check for updates if you're getting this holiday_service.py – often caused by removing a custom holiday; try a Save As to clear the error. load_from_persistable_sim_career_proto – known issues include removing school mods; try a “save as” in-game or play with the mod again. mc_career_dlg – caused by using the MC Command Center legacy version (which is for the game as it was in 2019), not the current version; delete the mod and reinstall the latest version min_lod_value – causes include outdated/broken custom traits; wrongly installed Andirz mods picker_interaction.py – causes include outdated PandaSama x Ravasheen toy kitchen; Piggy Banks, Oil Diffuser (Ravasheen); some Kritical objects restaurant_zone_director.py – mod-related causes include CC furniture in Restaurants scumbumbo_snippet – known causes include outdated versions of the SnootySims Camera mod; delete and redownload should_refresh_thumbnail – known causes include outdated Occult Hybrid Stabilizer/Unlocker mods or outdated 18+/NSFW mods state_py with _do_first_time_state_added_actions – mod-related causes include Custom Music Channels Compatibility Fix by Staberinde (delete this) trait_tracker – often caused by outdated custom traits, custom aspirations, and complex mods that include traits tunable_model.py, get_model – often caused by having recipes but missing the recipe enabler mod, having an outdated recipe enableer mod, or missing required packs tunable_perf (and also often TuningAttrCleanupHelper) – This error is caused by mods that were updated for a problem after Dec. 5, 2023 (1.103) ... and then Maxis fixed it on their end on Feb. 27, 2024 (1.105), so that mod fix now causes an error on game loading. This error is not an indication that there are other reasons the mod is incompatible with 1.105, but there could be other reasons. No error file can point you to which mods are the cause. Any script mods predating Feb. 27, 2024 should be checked for updates.

Issues That Seem Mod/CC Related but Aren’t This is a small selection of issues that tend to come to Mod/CC Issues but are actually game bugs or technical issues. Some of these can be caused by mods; please test first by dragging your Mods folder to your desktop, deleting the file called localthumbcache, and checking in your save again. Some mod-caused issues will need to you to do something else to clear the effects — edit a Sim in CAS (for some CC issues), a "Save As", to switch households and back, or something similar. Some can corrupt a save but a new save will be fine. Updated December 10, 2024 Bottoms of buildings missing after bulldozing Codes or blank bubbles instead of text without mods Doors visible with walls down Game Data Incomplete, grey llamas, red and white sims, broken textures on a Mac, without Mods High School prom doesn’t happen without mods Lagging in Live mode without mods – causes include too many unhoused Sims suddenly generated, social features turned on in Options, lots with too many interactable items for your computer specs, syncing software running during gameplay, large Tray/Screenshots/Saves folders. If none of these apply (test in a new save!), see this FPS-related topic or this topic LEs: posture errors – typically results from Sims having a tough time negotiating their way around objects Loading issue: lots or Worlds fail to load without mods (note: this also assumes you also couldn't get into the lot/world with mods and that you didn't remove mods/CC just before the problem started; if your problem started by mod removal, head back up to mod issues!) – [MASTER THREAD] Crashing and Endless Loading Lot type stuck on Residential Rental Trait slots are missing in CAS. Still not seeing your issue listed? It might just not have a major topic that’s been recently active! Please feel free to search for a recent topic or post a new one.

Crashing at the Main Menu – can be caused by removing custom tattoos (including CC) that a Mermaid is wearing. NOTE: This heavily impacts Mods folder testing but you can remove the save for testing too.
