Summary0012836: Constructed stairs still blocking stair construction
DescriptionThis is a 2022 issue that should've been fixed a while ago, since up- and down-stairs can no longer be constructed separately it is impossible to connect multiple flights of constructed stairs.
Steps To ReproduceDig a stairwell (m > t) into the ground anywhere, construct stairs (b > n > t) replacing the dug stairwell, remove (m > x) any of the constructed up or up/down stair tiles.

Rebuilding the deconstructed part of the staircase has now become impossible without first deconstructing it entirely, there is an up/down-stair tile blocking the player from issuing a new stair construction order.

The blocking up/down-stair tile can not be removed (m > x; m > u) without recreating the problem one level higher.

While the blocking up/down-stair tile can be converted into a down-stair tile by issuing a deconstruction (m > x) order it can not be converted into an up-stair tile, which would allow players to connect a new constructed staircase to it.
Additional InformationTo my knowledge there is no workaround/feature that can be used to quickly fix a long stairway that's been broken this way.

I'm not having any trouble doing this, including in a 50.15 version without dfhack. I don't get any blocking error. If I leave the top designation, then both z-levels get u/d stairs, but the top level's original construction material is gone. If I remove the top designation, then the original top z-level stays u/d with the original construction material, and new u/d stairs are built on the lower z-level.
