Summary0005866: Blocked path at a slope
DescriptionHello
I've seen plenty of pathfinding troubles here but I don't really know if they are related to this one.
I tried to dig (channeling) a few levels down on a young fortress. Until I found my miners dying at the bottom of the channeling I was doing.

with <=upward slope and >=downward slope and .=cave floor X=cave wall
for instance, lvl x:
XXXXXX
X<..>X
X<..>X
XXXXXX

lvl x-1:
XXXXXX
X>..<X
X>..<X
XXXXXX
and so on

Strangely the paths are blocked soon.
Steps To ReproduceLoad the game, you'll see that dwarfs will be able to go to the lvl x but not to lvl x-1. (all the stones on lvl x-1 are set to be dumped but no one comes)

Ramps do not work that way - you can only move up a ramp if the ramp is braced against a wall and the destination floor tile is above that same wall.

Valid Invalid
   __ ## __
__/## ##\__


If you look at the descriptions of those tiles, you will even be told that the ramps are unusable.

Not a bug - user error.
