Yeah same just happened to me. I spent multiple in-game days. I watched the structure events unfold of the days of the late teens and wandered all over the map. I even managed to fully steal the “chest” in my garage, temporarily, there in the middle. Can sleep in my bed or other locations. Can’t save. Eventually had to kill the game.
The whole disabling the in-game menu thing is not a good “feature” for so many reasons, but combined with bugs like this it is a game breaker.
