I've started getting a similar message, I built a house in February last year, and just come back to the game. I started a new game but I wanted to place the house I made onto a lot, which worked except it's an underground house, and the stairs down to the front door no longer exist, and when I try to place new ones there, it says "Incompatible with terrain constraint block", I've got Move Objects on, I've made sure I've flattened the terrain with the new terrain tools, and I've moved everything that could potentially block it but nothing's working, any help?
Also, off topic, but it's ridiculous you can't post until you've been a forum member for over a day, made over 15 comments, and earned 25 points (whatever that means), how am I meant to ask for help if I'm not allowed to post? :angry:
