So no one will ever be able to align walls/floors with sloped paths .-.The bug fix addresses building tilting. We've been really impressed with the way the community have used this bug. However, the feature was never intended to work in this way.

And we gotta hope that brand new assets are released like the "Upside down triangle wall" or the "Sideways pipe" [bored]
