Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? 1.77.146
What expansions, game packs, and stuff packs do you have installed? EP: GTW, GT, CiL, S, C&D, DU GP: Strangerville, Parenthood SP: TL
Steps: How can we find the bug ourselves? You can put your sims on the first floor, and then move yourself to the second floor. When you click something on the second floor, like the computer for instance and click "browse web", wait for your sims to come. Your sims will never come to the second floor to use the computer. The solution is you have to move yourself to the first floor, and you can see your sims just start to step up the staircase. They move only and if only your screen is focused on them.
What happens when the bug occurs? As explained above. Sims move through the staircase if only the screen is focused on the origin floor where sims depart. If your screen is on the destination floor, your sims will never move through the staircase.
What do you expect to see? I want things to get back to normal like it was before. Sims can move through the staircase even though the screen is not focused on them. I don't use any CC and Mods, and have already had the game repaired through origin.
Have you installed any customization with the game, e.g. Custom Content or Mods? Never used.
