The data size of lots has suddenly become much larger.

Since the May 12 update, the data size of lots has suddenly become much larger. I saved the exact same lot from the exact same save file, but the file size increased from 309 KB to 15 MB before and after the update. (I live in Japan, so the update actually arrived on May 13 for me.)

I have not made any major renovations to the house. I only added a few photos and paintings, and changed some of the platform/foundation floor types. The game shows the “modded” icon because I use CC for the household’s hairstyles and clothing, but I have never installed any build/buy CC.

I do not understand why the data size suddenly increased so dramatically.(ファイル=file)

I’m not sure if I chose the correct tags, since none of them seemed to fit exactly. Please let me know if I should change them.
