Sloped Greenhouse Roof Not Snapping To Wall

Only ramps snap to their short side not to the long side.

Sloped greenhouse roof not snapping to wall.

But not the basic. The sloped roofs snap to a wall or sloped wall. I m building a greenhouse. Very nice one too.

Is anyone else having this issue or know a fix. The triangular roof pieces work just fine. A ceiling atop pillars or snapped to an adjacent wall is sufficient. And they dont snap to their short side only the long side.

I put down greenhouse walls all around and now i just need to put on the roof. They keep trying to snap onto the foundation or even the side of the walls but not the tops where they belong. 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. 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.

Except the sloped greenhouse roof pieces absolutely refuse to snap to the top of the walls. Pipes can pass through the greenhouse walls. 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. However i see 3 sloped roof tiles not supported by any wall or ceiling tile from within the structure.

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. It depends on which side the wall is and where you stand if the roof goes up or down. So this looks like a support issue. Just place a few thatch walls to see how the roofs snap.

A greenhouse does not need to be considered enclosed. Im trying to build a roundish greenhouse and not put dividers all throughout it. Or do i need to make the walls out of wood or stronger.
