Summary0005077: Browsing world gen map causes corrupted feature files
DescriptionI'm getting an oddly specific crash bug on this map, in the ocean just south of the default embark location. Shift=down a few times and you'll land in it, and DF will immediately crash.

If default embark somehow happens to not be near it, it's the Indigo Seas, located on the left side of the map. Middle.

Save file: http://l4.selb.us/region2.7z
Steps To ReproduceLoad it up, go to the middle of the Indigo Seas, located on the left side of middle-map. Crash will not occur on edges, only when you go deeper inside.
TagsNo tags attached.

Are you using TrueType? If so, does it still crash with TrueType disabled?

Tested both with it on and off, and at it's default value. Crashes no matter what it is set to.

Thanks. Please reupload your save to http://dffd.wimbli.com/ -- sometimes personal hosting goes down for whatever reason and then we can't get the save.

Had this world been played? If so, what modes and for how long? The feature files are corrupted. Theoretically you can delete all the feature* files from the data/save/region folder to fix it, though that could have side effects. It'll be difficult to track the source of the corruption without more information.

 Nah, this was a newly generated world. I only looked around in legends mode and looked at the world map a bit.

Found the issue though. Data from exploring the world map isn't being cleared from /current/. Worldgen doesn't clear the folder, so it takes the existing files along with the newly generated world files.

Can you reproduce this problem in 0.34.02? A save corruption error was fixed in this release: 0005114

Yeah, I'm able to reproduce it in 34.02.

 Going to double post, sorry, but my findings are... interesting.
I've discovered this bug exists as long as feature files have gone into the /current/ folder while browsing the map. This seems to occur early in to the 31.## series.
This seems to have caused varying responses through the series. I reproduced 0002432 exactly in 31.08, so this may very well be the cause of that. Does not seem to occur anymore. However, extensive feature file corruption can cause a crash immediately on worldgen in 34.02 and 34.01.
Aborted worldgens also seem to leave their region files behind, but I'm not sure if this has any impact on the next generated world.

And as a bit of a buzzkill, I believe this is, in fact, the cause of the strange worldgen glitches such as the adamantine spire. I went through a few saves to see if I can see the same problem.

0005279 - Contains feature files created at the same time as worldgen files. Testing a neighboring embark with and without feature files confirms that they are the culprit.
0004163 - Contains a LOT of feature files created at the same time as worldgen files.

I can't confirm a link with the older adamantine spire save though, as every feature file for that has been modified and has different dates from the rest of the worldgen files.
But other adamantine spire saves found on the file depot do contain these files.

Corrupted feature files would certainly explain adamantine spires, since adamantine tubes are map features (along with rivers, caves, deep pits, magma pools, volcanoes, underworld portals, and the caverns/magma sea/underworld themselves).

Ah, awesome. I've been trying to figure out the corrupted feature files for a long time now, and I think that'll do it. I never abort out of embarks (if that's the main way to get it), so it hasn't happened for me during regular testing. The game'll now clear the current folder at various opportune moments.
