@DucksSauce Hiya.. sorry to read this is an issue your having.
No, it's not a common bug for most players.
Can you tell us if Mac or PC?
You say it's limited to script mods.. have you:
Deleted thumbcache
Started a new game with a test sim? IF that is working is it only the old saves?
Have you checked here?
https://answers.ea.com/t5/Mod-CC-Issues/Broken-Obsolete-and-Updated-Sims-4-Mods-1-104-Jan-16-2024-Game/td-p/13400494And Deaderpool's Discord for an expanded genre list of broken mods?
Verified your core mods are up to date?
Older script mods can and do often break saves or new games.
A good rule of thumb, script mods should be removed and only the latest update added when upgrading.
If none of that helped, you really need to remove mods / trays / saves to desktop and delete thumbcache
Repair game with the EA APP
Then start a new game with a new sim to test.
Then when working, you can add mods back 50 / 50 until you find the issue or all is well.
Then add trays / saves back.
Happy simming.
