The Official The Sims 4 100 Baby Challenge [UPDATED ON DEC 29, 2018]

And I just lost about an hour of play time due to the game getting stuck out of nowhere and not reacting anymore. I also have glitchy objects appearing in my game, like the bookshelf, washing table or even the easle. I wonder if anybody else has this? It is so very annoying, just like the fridge glitch which appears a lot. And I am not any further in the challenge, because I lost all my playing I did after that post.
