So, I have spent ages building a beautiful house, it's 3 stories high and just finished the roof, I then go to start my interior. As I was building (before my roof was built) I built some rooms just to try and create some sort of layout, but then I wanted to delete them and start again. I kept getting the error of 'nothing to change' and 'nothing to delete' when there was clearly a wall to be deleted! Also, kept getting the message 'op generation failed' Why is this happening?
It's only after the building of roofs that I have noticed this problem. I've tried deleting the roofs around the room and things but honestly, nothing is working. I hope this is fixed in the next patch cause it's really making me not want to play anymore.
