...and they aren't pretending to either.
As much as housing is essentially a sub-trap, I enjoy my 2 virtual storage boxes. It's neat that as of 7.1, we can change interiors to the minimalist design or any of your choosing.
Apartments are snubbed from this.
When we eventually get the item limits bumped, i'm sure apartments will be snubbed from that too.
Small House with Larger interior future update? Nah, Apts likely won't get that either.
For people who want instanced housing, the solution already exists. Right there, IN GAME. But RIP, you're stuck with a 100 item limit closet because; Apts are just another abandoned piece of content that won't recieve any more updates.
