Sims 4 wont save after playing

So i've been having a lot of problems with my sims game recently. mainly with my saving. Originally my game wouldn't save properly at all. I would press save and it would be stuck continuously saving for hours, so i'd try exiting the game and trying again which ends up with me losing various hours of gameplay. I thought it was because of my high graphics, so i turned it down to just high and it seemed to fix my problem... but at the time i had just loaded the family in and only did a handful of actions. I think there's a problem with my game and saving once I actually start playing it and it's kind of devastating as I went through already 2 hours of the house and the godforsaken save trap is still happening to me. I know that my mods probably contribute to this a little seeing as I have 1,000+ of them downloaded but I really don't know what's causing the problem? can anyone help me?

oh and whenever this happens i get the little sandtimer icon next to the cursor when i save, which im assuming indicates that its lagging/experiencing a problem with the save screen. and whenever i save i use just the save option not the save as or save and exit.
