Things are missing when loading into a lot

After the new update, I'm experiencing an issue where toilets, sinks, stoves, refrigerators, all electronics, and lights disappear on all lots – both where my Sim lives and on other lots as well. I've tried restarting my game, removing all MODs and CC, I have also started a new savefile, but nothing helps ...

Has anyone else experienced a similar problem and maybe found a solution? 

It's starting to get really frustrating (and expensive!) to keep replacing everything... 😑
