Shrodinger's Wall

[WolfSpiderHell24]

I was building an expansion to my house/base and i tried to delete a wall to make way for a door frame, but when i deleted the wall, it dropped two grass planks but didnt "technically" delete the wall. its almost as if its stuck in between existence and non-existence. I can still see the wall, and i can still collide with it, but when i jump i clip through the wall. I cant recycle the wall anymore, implying that it is indeed not really there, but i can place blueprints for wall decorations such as Trophies on this non-existent wall. what happened and is there a fix?
