Spontaneous Combustion

[Zedrin]

So, I recently opened up the magma sea in my latest fort.

Made a lot of progress preparing ramps to bring magma to the surface via minecarts. Then my game crashed.

Now, any save I load, fires immediately break out in my stockpiles near the surface. This didn't happen while playing and spending a *lot* of time mining out paths and ramps. It also happens in the exact same areas, regardless of what save I load.

Anyone know what's happening or how I can minimize the damage? I don't want to lose my entire fort to a bug.

Temperature has gone nuts maybe? You can spawn in water with DFHack but if it is temperature, there's going to be bigger problems. Like dwarves melting.

Sounds like a temperature issue. Reload an earlier save and disable temperature. You might be able to re-enable it at a later point without issue.

It may also be a save corruption issue, based on the description of reloading a save after a crash.

The source command does not appear to work currently, so that's out the window.

Will turning the temperature option off temporarily help maybe? I don't know, just guessing. Maybe some other setting that will help.

Result of kitten on yarn friction, probably.

Do you have any magma crabs on the map, or similar magma-inhabiting creatures? Maybe one of them snuck in, they like to mess with your fortress as soon as they have any path into it.

Or UristMcLemming saw something that got lighted up from 1-tile of magma (like discarded clothing) and decided to "clean" it up by bringing it back to the stockpile?

I think you're approaching this from the wrong angle, though. The question you should be asking is "how can I reproduce this for weaponization purpose."

Hope you got seasonal saves on. I just lost almost full season to a strange mood bug myself, and that included babysitting carpenter's workshops (to prevent my usual carpenters from involvement, because I don't want Masterwork sticks pocking into the recruits and children) to produce just low-quality wooden training spears in sufficient quantities to fill every other tile of a 10x20 room... Then building all those traps, and linking them ALL to the pressure plates. Danger Room will double as training swimming pool with enough water for some 4/7 pressure to not just train swimming, but also trigger the spike traps.

So... yeah, a LOT of work lost just because some agitated raven decided to peck on my "Strange Mood" hunter so he bugged out. Whom I don't want to lose, because he's intended to be the captain of the guard with the spectacular stats he started with.

pump stack is less dangerous. magma is hot.

Also, unlike minecart tracks, prevents mobile !FUN! from moving in.

pump stacks are too much of a pain to build tbh, and I don't need a lot of magma. Just a few 4/7 puddles for some forges in my workshop area.

Either way, I just walked back to an earlier save, quite a bit earlier unfortunately, but I got things operational way earlier. It was weird, like my 3 last saves *all* had the fire problem, and all in the exact same spot. Like a burning object was in the stockpiles a while back, but was inert until I reloaded the map.

I've had something similar happen and its definitely a bug, something was probably hot enough to catch on fire but didn't for whatever reason, when you reload the save the temperatures get rechecked and the thing catches fire,

Had it happen to me with a random animal that died to a fire breathing forgotten beast, one of its body parts ended up in a refuse stockpile I had on the surface, loaded the save later and let it go for a bit, when I looked at the surface to do some trading half the map was on fire.

Agreed, and why I build magma forges right beside the lava, or wells beside the water in the first cave. Just have to make a safe route to them, that are not connected to the caves, and stop critters/invaders entering from below.

You have some fire snake roaming your fortress, and since they're vermin, they're ambushed about 80% of the time. Without cats, you're hugely ♥♥♥♥♥♥.

I'm playing with the Roclets mod, so my citizens themselves as well as the hordes of emon I have all hunt vermin when they see them.

The thing is, the fire was spawning from different saves in the exact same spot. No fire, then as soon as I unpause after loading, huge swathes of flame in fixed locations, regardless of which save I loaded. So as someone suggested, it probably was some items got too hot and moved to the stockpiles, but the temperature didn't update until after the game reloaded.
