build and buy won't let me place new items or change colors

since the most recent update my build and buy does not work anymore. I can not place new items or change the colors of already existing furniture in the build that I placed before the update. Wallpapers are also bugged. I can not change them. somtimes a new items does place but then I can not delete that item or change it place. build and buy basically does not work and it makes playing the game impossible.
