Product: The Sims 4
Which language are you playing the game in? English
How often does the bug occur? Often (50% - 99%)
What expansions, game packs, and stuff packs do you have installed? All
Steps: How can we find the bug ourselves? Select a lot, go into build mode, choose a few different floor patterns and create some designs with them. Save the lot to your library. Choose a different lot, go into build mode, and place the lot you saved to your library on the new lot. Note the floor pattern designs.
What happens when the bug occurs? The floor patterns will often have changed orientation on the new lot.
What do you expect to see? I expect to see the floor patterns remain in their original orientation regardless of which lot they are placed on.
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
This issue was originally reported in this thread. Below are images of the problem in action.
1. My original floor pattern designs when created on "The Summer Home" lot in Windenburg:
2. How the designs were changed when the lot was placed on "Dresden House," also in Windenburg:
Another old example is the Rock and Roll House on the Gallery. If you place it on the Affluista Mansion lot in Oasis Springs, it's floor patterns are correct, but if you place it on virtually any other lot, their orientation changes.
