Sims 4 update March 15th broke my game.

So, since the update of march 15th, the game (Sims 4) is now completely impossible to play for me. I can't change anything to a house in build/buy mode anymore, I can't save and exit the game and if I use the "save and go to manage worlds" button, it just gets rid of ALL of the gameplay since the last time i saved before that time. This is just one of the many bugs I have now: in the top area in Mt. Komorebi, the eco footprint disappears for some reason. And on top of that, the 'update' part of this (the neighbourhood stories) is also broken for me. Oh and that's still not all. My sims' friendships are spontaneously disappearing. And sometimes if I sell things in my sim's inventory, I get the money the item was worth but it remains in their inventory, I just can't interact with it anymore. Oh and if I want to make a sim split from a household and move, the game thinks that the sim I wanna move isn't in the world and has no family.. Before you ask, yes I've updated all of my mods and tried again, yes it failed to work correctly even after that. I then took all of my mods and cc out of the game and the game was still broken. I'm just amazed at how little effort the Sims team puts in checking if the updates don't break anything. I should not be ranting on here about a game that doesn't even work which i paid a lot of money for (DLC).
