(example of household icons/images not loading)
I believe it started when I went to edit an NPC in CAS while my sim was at University and the game froze. I discovered I couldn't travel with that NPC in my PCs company but I could invite them over (worth noting that NPC had minimal to no CC). From that point, it got worse; moved my sim to Sulani (she is a second generation sorceress - virtuoso level - who I played through University for her honours degree). I got her into the conservation field and living on Mua Pel'am and things got increasingly more glitchy. The weather glitched and stayed like Britechester's until I did a factory reset. Then, three days into her life in Sulani, the game didn't keep up with an outfit change after she was in the waterfall, leaving her icon on the sim panel blank (worth noting a lot was going on, graphics-wise, as there was an intense lightning and thunderstorm happening). Game could not save afterwards. I was able to progress again after repairing game but the problem is back and now every household in this save file is affected, even those in different home worlds (like her mum in Glimmerbrook), making me unable to play it because progress cannot be saved (due to icons/data not loading). Repairing the game, again, makes it so the daughter's household icon loads but others in the world do not, leading to the game freezing once more.
I've removed my mods and cleared the caches. I delete the localthumbcache after ever close. I've repaired the game multiple times as per the guides. I've done a reset twice and played a clean save with no issues. Going back to this save and it is still broken. I'm super bummed and desperately wanting to know I didn't put all that time into a save file that is now unplayable. I apologise in advance if the lingo isn't quite right but I'm not 100% sure of the correct terminology for things and none of my googling got me anywhere. I did, however, see a reply to another issue on this forum that mentioned the game being unable to save when the icons don't load because the game isn't able to play catch up and that is definitely what is happening here.
** All of my mods are up to date (as far as I can tell). I use Driver Easy to keep all my drivers up to date (and everything is up to date, I manually checked). I use Restoro to make sure my computer is running efficiently. I've checked all my mods with ModConflictDetector and nothing appears out of the norm.
EDIT I was able to play her mother's household and save but going back to the daughter's still resulted in the gave being unable to load the portrait panels and outfit panels and, thus, unable to save. I might resort to having the mum move the daughter back in but I'd rather not lose the house and everything else back on Sulani. Feedback welcomed. Additional pictures of being unable to save the daughter's household to my gallery and of her outfits not loading. Cheers.
