Summary0000225: Cannot find path to build bug
DescriptionI built a staircase down a floor from the surface in order to install floodgates and establish a system to drain water from a surface pond. Later I expanded the tunnel in this area, but later decided to give it an entrance from within my fort as opposed to out in the middle of the wild, so I removed the existing staircase and dug out a new path. However, when trying to install another floodgate after the new path was created, it would not allow me to place one on any tile other than ones I had just dug out and the immediately adjacent tiles, citing an inability to reach a non-economic material.
Steps To ReproduceDig a path accessible only via stairs. Remove the stairs and build a new path to access it. Then try to build a floodgate or other piece of furniture on various tiles on the path.
Additional InformationDigging adjacent tiles allowed the area to have things built on them again.

This can also be reproduced with ramps. I channeled out the edges of a cistern to widen it, and channeling now leaves ramps.

I later decided to expand the cistern and line it with stone, and mined out the ramps, but when I tried to build walls where the ramps were, I got a, 'cannot access non-economic stone' error. Also all the dwarves in the cistern won't leave it, no matter how many new direct routes I mine out. They sit in the middle, slowly dehydrating.

What is odd, is I can place wall jobs INSIDE the cistern, in the area I hadn't dug out, but as soon as I stray into the mined-out ramp area, the area designator won't let me place anymore.

My issue might be related to this:

I dug down with up/down staircases then trapped a dwarf by building over the bottom one with a floor. My later attempts to free him by digging a new staircase next to him failed with "Could not find path.". I was able to build 2 tiles away from my stuck dwarf and rescue him by doing a normal ('d') mine.

This and other issues are being marked resolved because they fit the symptoms of the general pathing bug described by issues 0000018 and 0000070. If this issue represents an additional bug, it will most likely present different symptoms in 31.03, and a new report should be submitted.
