I played Sims 4 a couple of nights in a row. I was able to load my existing family on the second night. But today I can't even find the load game button.
There are two ways to load the saved game. One way is to just pick the play button in the bottom right corner of the loading screen. It brings up the screen to access the neighborhoods. The other one is in the top right corner of the loading screen. There are 5 icons there. It's the second one to the left. A popup menu should come up with your saved households. Is that not coming up for you or are the icons missing?
