How often does the bug occur? Every time (100%)
What is your current game version number? 1.63.136.1010
What expansions, game packs, and stuff packs do you have installed? All but Fitness Stuff and My First Pet Stuff
Steps: How can we find the bug ourselves? Place lot with flower arrangements from gallery/library
What happens when the bug occurs? Flower arrangements in lots look odd when placed from your library/gallery. Vases and flowers are not preserved, and instead use the default vase and have four tall, skinny flowers instead of how the arrangement originally looked when the lot was saved.
What do you expect to see? Lots placing with flower arrangements and vases that look like the ones saved with the lot.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure
I found the bug when I saved a lot with flower arrangements and then placed it again from my library to test it, but I replicated it multiple times with different types of lots. Flower arrangements in the original lots I saved weren't from debug mode, they were crafted by sims. This happens for every flower arrangement and vase that was saved with the lot; it doesn't seem to depend on the type of arrangement or vase. It also doesn't depend on the quality of the original arrangement; almost all of the ones in the original lots were excellent quality masterpieces made by sims with high flower arranging skill. The name, quality, and scent of the flower arrangement are still preserved when the lot is placed. The names of the sims who crafted the original arrangement are also preserved when the lot is placed in the same save. I made a save file with a few lots with flower arrangements (all in Newcrest), both the original lots and the duplicate ones I placed from my library, where you can see the bug.
