Product: The Sims 4
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What expansions, game packs, and stuff packs do you have installed? All
Steps: How can we find the bug ourselves? Place a flat and raise foundation a few notches. Place a non floating stair onto the flat at one edge (the stair should extend one tile out from the flat rather than being entirely upon it).
What happens when the bug occurs? After placing the stairs, if you move your camera or adjust your view, you will see flickering on the upper portion of the stair near where it intersects the flat.
What do you expect to see? No flickering when a stair is placed in this manner.
Have you installed any customization with the game, e.g. Custom Content or Mods? Never used.
Did this issue appear after a specific patch or change you made to your system? No
