Played/Unplayed Sims in Newcrest are kinda cooked
in one of my save files, when i either try to edit my Newcrest played/unplayed sims either in gameplay mode or world editor mode, for some reason the loading screen just keeps loading and loading for so long (usually it takes like 3-5 seconds to load successfully), then a better exceptions mod page came out and it showed a UI exception scanning page thingy which took a long time to scan (idk how long it takes to be frank 💀)
but when i checked out a (played) household in another world such as Forgotten Hollow, and entered cas through world editor mode, it loaded successfully for some reason
uninstalled a bunch of UI mods, reinstalled some pose packs for cas (bcos im sure this only overrides the default trait animations and had nothing to do with UI) and deleted off a few small utility mods (including BE bcos im scared it might create more bugs), used a mccc setting to delete an outfit one of my sim bought and wore from a GTW mannequin in hopes that it works (bcos UI Exception scanner said smth like "in-game dialogs dont work in CAS, build buy and more", smth like that) but it still keeps on loading for a long time
is newcrest somewhat broken or are my mods making newcrest uneditable, or are my newcrest sims broken?
