Help? "Incompatible with Terrain Constraint TerrainTile"

This is happening to me every time I try to place stairs inside a garage or sunk living room. It is driving me nuts. I posted to EA answers here. https://answers.ea.com/t5/Bug-Reports/OPEN-Stairs-go-way-into-ground-when-placing-stairs-near/m-p/7213982 Although now the problem is moreso the terrain constraint and less the stairs going into the ground. I hope this problem is fixed soon.

I've had this issue a few times but changing camera angle seems to fix it for me. Its almost like the game thinks I'm trying to make the stairs go lower than the terrain and usually only happens when my build has a basement or an unusually high foundation. You might try changing your camera angle. I think the game is trying to build the stairs into a lower floor that may or may not exist when your screen is pointed in certain directions.

I could be wrong but it does seem to fix the problem for me so ...that's something at least.

Thanks Holliebrooke -- this worked for me.

I was having the same problem but I think I figured out a solution. Whichever room you want the stairs to start at, double click to select the entire room. Then an option to "build floor" should pop up. Select that. After that I was able to place the stairs. For some reason it kept thinking I didn't have any floor tiles there even though I had placed them...

This does NOT work for me as I want the room to be a sunken room. When I build a floor it raises the sunken room back up onto the upper level's foundation and no stairs are then needed. When I remove my floor tiles on the sunken level THEN I can place stairs, but it morphs my terrain and forces a long angled staircase to be place from a ditch up to my bath tub in the bathroom. I bulldoze the terrain and the stairs are gone. I just want one step up. That's all. :(

I just got the same issue with a sunken room..

Thank you, thank you, thank you!!!!! I was so ticked off I just about bulldozed the lot to start over. This totally worked for me.

I was having the same problem when trying to build sunken rooms...the stairs either go miles into the ground or give me the 'terrain' constraint terraintile' message. After messing around with it, I accidentally discovered that it works for sunken rooms if you delete 1 grid of wall (any wall in the room with your stairs; you can replace it after finishing them) to delete the ceiling over that room. You can replace that part of ceiling by drawing walls on top of that room to cover the entire open room. (Those walls can also be deleted afterward if necessary.) Without the ceiling/foundation, it seems to give you more freedom without the funky problems! Hope that helps!

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:

Heyyy,

This was my very problem for like the last two days, I don't really have a brill solution but its what I've done.

I think its something with it being a complete room hence the word "lot edge" so what I did was just make two separate walls then made them to fences and at the corner I just didn't connect the walls and then I could put in my stairs. that then means I have a gap so to fill that gap I added a second post box. lol.

its deffo a weird rule!!

So what worked for me was I deleted the doorway and the part of wall where i wanted the entrance.
