Oh my. I didnt even think of the interactive item limit problem!

Yea we need a way to disable these walls to lock them as mentioned. A good way to do this could be a toggle option. "Lock walls" to prevent the wallpaper change or so.

Issue in FC houses is this. Everyone can access the walls. Now that alone doesn't create an issue.. What IS an issue right now are limited edition seasonal walls. Ones that used to be buyable and MB buyable.. now are only on the mogstation buyable.. and when you need least 4 or 5 wallpapers for a room.. So either you spent 500k per wallpaper or few $$$ on the mogstation, would SUCK to see someone replace it on you and then its unrecoverable.
