[LN or Base Game] Rabbit Hole Replacements (The Rugs are back!) (Pets Fix)

[Omamemmie]

Thanks for this, I love the rugs, they allow me to build my city my way ;)
Question though: I created this community lot and assigned it to be a library, then I placed the rabbit hole rug for the police station on it, cause I wanted this lot to contain two buildings: the library AND the police station. However, when I go into Edit Town mode I can select the lot and it says library, but when I go into lifemode and select "View town" (or whatever it's called exactly), the lot only appears to be a police station. So there's "no library".
Do I need a special set of rugs for community lots or is what I'm trying to do just not possible?

Thanks in advance.
