i've been building some rental units. all was fine but i noticed weirdly it still had the rental icon on the manage worlds screen even though i had made it a normal residential lot when build mode for rentals was laggy. it also showed "rental units" (despite no longer being a rental lot) for like 4 million simoleons, and when i clicked on the lot to go into build mode it would go to the view for residential rentals where it has like the up and down buttons. whatever, i thought it must just be one of my mods needing an update. (i'm not sure if all that was happening before the 12/14 update).
anyway, today i was just building and accidentally hit f1. oops. but then the loading screen was eternal! so i force-quit the game and when i opened it again...the save i was building in had somehow merged with another older save???? like the played households from each save were there, and their houses were the same. and when i tried to go to san sequoia, where i had been building, it just straight up didn't load. just a white screen. but i could still press esc and exit the game and all that.
ADDITIONALLY, i had switched the build from the og save i started it in to another one (og was not the one that merged, it was the second one) in hopes it would fix the ui issues. but now san sequoia also doesn't work on that save even though it did literally a few hours prior.
and also it's still broken with mods disabled. so that's cool.
