The save would be useful, but what might be even better is the world gen parameters for that world (you can export those from Legends), plus a screenshot showing the location of the cave (on the embark screen, or a Legends historical map or whatever). You can upload the screenshot to http://tinypic.com/ [^]

Poked around underground - no entrance from the caverns and excavation of the area beneath where the cavestuffs are reveals nothing.

Here's the worldgen export. I have also removed the raw entry for bronze collossi (trust me - you would have too if you were embarking on caves). It could possibly be related to that...but I don't see how. In any case it would need to be done to get the same world.

Also note: this one's a doosie. 1400y worldgen on a large map.

I think I may have determined the cause for this. I am seeing this occur in cases where the cave icon appears in the path of a stream in the world map. Probably worldgen gets confused about how to put a cave in a stream and screws it up like this.

If this is the case, then a simple fix would be to have worldgen simply NOT place caves on tiles containing a stream.

I found an identical issue.

I embarked on an area where a cave was placed on the same tile as a river, and found no cave whatsoever. I did find a bronze colossus charging at my dwarves, however.

Confirmed here as well, .06. Same -- the cave pile, with all its goods, is centered on a brook, and there does not appear to be any sort of mound.

This is still present as of .40.09. I've embarked on a few caves recently and encountered this bug several times when finding one placed on a water feature. It has occurred in several worlds with a wide range of settings, and I believe is easily reproducible by setting caves to be visible in advanced world gen and just looking for it specifically. I've just generated a medium world where I found four instances of it, without having increased the cave count, and only slightly increasing cave size. The world gen parameters:

There were a few rejections during world gen, so it may not create the exact same world. However I embarked and immediately saved on three of the caves I found like this (I couldn't find the fourth again), and can provide the saves (or a clean world backup). I'll repeat, though, that I've found this easy to reproduce in a variety of worlds across many versions.

Probably worldgen gets confused about how to put a cave in a stream and screws it up like this. If this is the case, then a simple fix would be to have worldgen simply NOT place caves on tiles containing a stream.

(0007586) JohnLukeG (reporter) 2010-06-02 16:27	I found an identical issue. I embarked on an area where a cave was placed on the same tile as a river, and found no cave whatsoever. I did find a bronze colossus charging at my dwarves, however.

I've embarked on a few caves recently and encountered this bug several times when finding one placed on a water feature. It has occurred in several worlds with a wide range of settings, and I believe is easily reproducible by setting caves to be visible in advanced world gen and just looking for it specifically. I've just generated a medium world where I found four instances of it, without having increased the cave count, and only slightly increasing cave size.

However I embarked and immediately saved on three of the caves I found like this (I couldn't find the fourth again), and can provide the saves (or a clean world backup). I'll repeat, though, that I've found this easy to reproduce in a variety of worlds across many versions.
