Summary

0006390: Trans-cavern passages sometimes have an incomplete ramp (blocked by a floor tile), making travel through it impossible.

Description

While spelunking using a modded creature and sometimes using DFhacks reveal to assist in finding the passages, I've noticed that while the passages themselves are complete, they often have a spot where there is an up ramp, but there is no corresponding downramp above it, just a floor blocking the way up, or down depending on direction of travel.

It seems to happen more often at the floor of the upper cavern level but I've had ones that are blocked off at other points. The announcement triggers as normal.

The passages are common enough that you'll eventually find one that you can go through.

I've also had these a few times on an embark site.

Steps To Reproduce

Take an adventurer into the caverns and explore around, investigate every downward passage until you find one that you can't go all the way through or get an announcement of a downward passageway with no actual access.

Although if you use DFhacks reveal (or the dev tool equivalent that Toady has, if any), you can just walk around on the surface and look using that.

These are the cavern worldgen params I use, but the parameters shouldn't matter.

Notes
(0024216) smjjames (reporter) 2013-11-19 10:30	Also, just to add a bit of a note, since Toady was working on the underground sites and may have changed worldgen related things, it's entirely possible that it got fixed along the way in the next version. Little bit surprised that there wasn't a bug report on this already, but at least there are ones which are passable all the way through.
