There are countless frequent examples of recycled content. Like the hair from C&D for males is copy-paste and are barely different. Parenthood added exact same raccoon outfit from CL. They could have just patched in or added as a color swatch to the existing item, but nooo - wanna give an illusion into tricking "LOOK! new cas asset/item" by having lame-ish justify their poor budget or lack of creativity. Animations are also too frequently recycled, the broken retail system (pretty predictable it was that vet clinic would turn out to be buggy as a store), the retail table, the rugs that come in two objects (separated & overlapped in a shape). Imma make a comparison between TS4 era & TS3 era recycled content quantity to see how much of a significant difference they have.
