Multiple stair textures are misaligned depending on the orientation. Most often when facing south as well as west and placing a stair down the stair textures of each surface will not be aligned with each other. This makes for a very odd looking staircase when placed in this direction. 

It should be noted that this affects all stairs where straight lines define the textures, although some are more noticeable than others. 

The most obvious cases are in stone brick variations. 

I will attach pictures below to demonstrate this as well as other textures that are less noticeable.
