sims 4 tiny living...the floor is reflecting the sky? / floors not showing up

@FeistyMcFeisty That is a graphical artifact if the home was from the gallery did you install tiny living with mods in game, remove mods from game by dragging out the folder and go into origin and hit repair game. and run game without mods to see if its back to normal, make sure patch is up to date. It does look like the sky but its actually the bottom of the simulated world. Game can't find floor tile textures because they changed name or not present.
