Yes, you read it correctly! It seems that The Sims 4 1.66 isn't only against CC Windows and Doors, but also against many mods, and there's not much you can do about it, short of updating everything possible and possibly removing some of the mods.
🌌 Released on September 8th 2020, it's available for you to download and install right now! Check out what's in store for you and if this is your cup of tea. 🤦🏻♂️
