Sloped Greenhouse Roof Not Snapping To Wall

However i see 3 sloped roof tiles not supported by any wall or ceiling tile from within the structure.

Sloped greenhouse roof not snapping to wall.

They keep trying to snap onto the foundation or even the side of the walls but not the tops where they belong. I m building a greenhouse. And they dont snap to their short side only the long side. Just place a few thatch walls to see how the roofs snap.

Except the sloped greenhouse roof pieces absolutely refuse to snap to the top of the walls. Engrams for greenhouse wall and greenhouse ceiling are unlocked at level 42 greenhouse doorframe and greenhouse door at level 43 and the sloped components at level 44. The greenhouse wall and greenhouse ceiling cost 30 engram points to unlock while all other greenhouse structures cost 15 engram points. Very nice one too.

So this looks like a support issue. Pipes can pass through the greenhouse walls. Im trying to place a sloped roof but it keeps on snapping to the floor how do i get it to snap to the walls. A greenhouse does not need to be considered enclosed.

The sloped roofs snap to a wall or sloped wall. But not the basic. The triangular roof pieces work just fine. So you cant start a sloped roof with the ceiling or floor only with a wall.

Im having an issue with the sloped greenhouse roof not snapping on top of a ceiling without being supported by a wall to the side. You can build a wall up from the bottom foundations to the center of the roof tiles you re trying to place or you can try putting ceiling tiles across the center of the structure from one side of the roof. I put down greenhouse walls all around and now i just need to put on the roof. Im trying to build a roundish greenhouse and not put dividers all throughout it.

Is anyone else having this issue or know a fix. Or do i need to make the walls out of wood or stronger. Currently only have thatch walls and im getting irritated with getting it orientated right and no matter what button i press i cant change it.
