Buildings missing from marketplace?


Seems like 2 buildings - I can’t remember their names, maybe “manga mansion” and “mini manga” or something, have been removed from the marketplace. Too bad, I liked them but have deleted them from my domain, so I suppose they are gone for good? Is that normal, that people will upload and then later remove content? What if I’m using that content, will it be deleted from my domain?

UPDATE: I’ve figured out that those objects won’t be deleted, since I see them on other domains and it’s now obvious to me that there is no connection between an object in the market and the copy of the object I download to my domain.

Still, I’m curious about this. Why would someone offer up an entity and then decide to remove it?
