I cannot place objects in Build/Buy

Hi,

Since the update with the new bunkbeds, I can't do anything in build/buy... Not entirely true, I can move objects that were previously placed and build walls if I press B but can't put any wallpaper on them. I can't place any new objects, I can't change the colour of already placed objects... I tried taking out my mods that mess with the script of the game (like MC Command Center, etc.) but t didn't change anything...

I don't know what else to do...

Can someone help please?
