Summary0002163: Objects dropped from above (such as stones from removed constructions) get stuck in fortifications
DescriptionOver time, I have been building a tower. Construction begins from the outdoor scaffold so I don't leave my fort vulnerable to flying invaders.

My fort design, built from the side, is as follows:
+ = Fortifications
_ = Floor
X = Stair

____________________X
+________X________+ X
+________X________+ X

As I build up, my design forces me to remove the constructed Floor over my Fortifications. The result is, the material falls into the Fortifications and cannot be retrieved except by the removal of the Fortifications.
Steps To ReproduceBuild a Construction directly above a Fortification.
Destroy the Construction.
Your building material will be stuck inside the Fortification.
Additional InformationThis is definitely related to 0002160, and probably caused by Fortifications not providing a Floor above them.
TagsNo tags attached.

# Req134, FORTIFICATION OBJECT PROBLEMS, (Future): Lost projectiles in fortified squares can cause complications. You should be able to retrieve them somehow.

# Bloat294, CLEANING ADJACENT INACCESSIBLE SQUARES, (Future): There should be a way to clean chunks and other garbage out of fortifications or other places it gets stuck.

I've also been having this issue in my fort with 31.12
I built walls, then carved into fortifications, 3 z levels on top of each other. When I decided to deconstruct a portion of it on the top level the stone fell through causing the square one level down to have both a stone and the fortification there, but the fortification no longer provides a floor above it like it did before.

Pretty sure they never provided a floor.

Walls that have been carved into fortifications don't have floors on top? My dwarves seem to walk on them just fine...

Here is a picture demonstrating this issue. http://i.imgur.com/4rXVm.png [^] [^]
The image on the right is 1 z-level above the image on the left. The two olivine stones and silver block dropped through when I deconstructed two walls and a ramp on the higher level.

Fortifications that have been carved (whether out of a natural wall or constructed) have floors above, just like walls. Constructed ones don't.

The bug is here - falling and flow-moved objects (and babies) get stuck.

This means OP could circumvent it by building a wall instead, and carving fortification into it. You still get 2 jobs ("build, carve ... build, carve" instead of "remove, build ... remove, build"), and removal of constructed floor is also buggy, after all.
Unless having open top is necessary for some reason (let water in?) - which perhaps could be solved by building a "sink" elsewhere.
Aniother way to circumvent this bug is using a floor hatch (or grate) instead of that floor - these can be walked upon, block passage (though not for everything), and removed hatches are moved to the next tile, not allowed to fall.

Also, for some reason, an earlier ticket was marked as a duplicate of a later. Oh, well.
