Since the update last week i have been having an issue with floors and walls disappearing as i fill them in. this is happening in several locations on the map so it is no an isolated ins incident. It is also happening with all wall/floor types. Weed stem, grass and mushroom bricks. All of them are inconsistent and disappearing randomly but they are still there preventing you from walking through that space.
I have been running into an issue where I am unable to place floors or walls when in certain areas. If I am on the ground I am able to place the walls and floors. but if I go up one level, two stairs, I am not able to place anything. This issue started about a week ago and have not been able to find a solution for this since it began.
