Summary

0006387: Cavern regions with high water content interfering with demon fort placement? Also no cavemoss or fungi on cavern 3

Description

I have no way of testing how many demon forts there are in a given region, but since I had little trouble finding demon forts in other regions and in this huge region the save is in I've explored for hours in this area which seems to have something like 70% water coverage, I've only seen one demon fort. While in an area of comparable size, I found four at least.

The other cavern features (except for maybe the trans-cavern passages and deep pits, but haven't been paying attention to those two specific features) appear in what seems like normal quantities.

This region is also notable for not having cave moss or floor fungi, but that is trivial since the upper two have that and it'd be easy to re-seed the cavern with the spores.

Steps To Reproduce

This is the worldgen I used, although the history might come out a bit differently.

Outside of using this worldgen:

1. Generate a world with potential for caverns with high water coverage (the settings below should do the trick.

2. Start up some adventurer, descend into the depths (though it may help to use DFhacks reveal to see what the cavern looks like below before descending).

3. Explore the region that has high water content.

4. Count how many demon forts you find and compare to a less watery cavern region.

Notes
(0024193) smjjames (reporter) 2013-11-03 08:16 edited on: 2013-11-03 12:13	One thing that I've noticed is that regions with these odd third cavern layers seem to have no problem producing wildlife while other regions are just devoid of wildlife, or it's so sparse that I never manage to encounter any. Ramp issues are also common in these regions apparently. There also seems to be a bit of a problem connecting westward in the area where I am, but eh, cavern is a maze anyway. Testing out another world with the same worldgen settings and different seed. I did find one, though it doesn't seem like forts are able to generate very well where there is lots of water. Toady One did some changes (complete overhaul?) to demon sites, so the question on the fortress generation is probably moot. The no moss or floor fungi could be looked at though.

(0036813) Loci (manager) 2017-10-29 11:31	Demonic fortresses were removed in v0.40.01, but according to the wiki prior versions would generate one fortress per 16x16 embark square, which is fairly rare. Caverns occasionally generate with a Subterranean Chasm biome, which only supports very limited flora (bloodthorns, specifically). This behavior is likely intentional.
