Summary0000884: Blood pools propagate through distant water flows
DescriptionI dug an aqueduct 10 levels deep from the river to a cistern, and of course made a mistake in the planning and filled it too full. A short time later I dug a relief corridor to the middle of the aqueduct. As soon as the water-filled shaft was breached, blood spatters and pools spread to the surrounding tiles, tagged as belonging to thieves and animals dead more than a year.

Where were the blood spatters and pools originally from? Were they in the river, or on your dwarves or what?

Water is supposed to spread blood around to an extent, although it's wonky right now (see 0000296)

I saw a note about this on the wiki as well. let me copy that here for you.


I've built a very large reservoir (currently 30x25x4 approx) on some ground that had mountain goat blood on it. There is also a small amount of mountain goat and dwarf blood on the area around the reservoir. On overflowing the reservoir (which is fed from the top by a "clean" source), I get blood EVERYWHERE the water flows, seemingly on evaporation of the water. There's now far more blood spread around than the creatures had originally... anyone seen similar? --Nimblewright 21:21, 8 April 2010 (UTC)

Almost certainly [^]

and not a bug. The blood got washed off your miner's boots when he got wet breaching the shaft.

read 0000296 more closely. washing off a smattering or smear does seem to be as expected. but once a pool of blood is involved things break.

adding a 7/7 tile of water to a single pool of blood in a controlled manner, created about seven new pools of blood. The behavior described here refers to blood from a single goat flooding out to many many tiles as the reservoir overflows.

Maybe I should go make a video to quiet up the doubters.

Here, a visual example, easily replicated in the arena. First the control, One dead alligator. [^]
The alligator generates two pools of blood, one smear, and one spattering. Tracking this blood around can spread it into five spatterings and four smears. [^]
Now going to a clean spot, and killing a different alligator and this time, adding water. Using a combination of tracking the blood around and adding more water, the amount of blood in the second example increases very dramatically.

Yes the spread of blood is totally out of control when water is involved. I'm going to make an automatic dwarf shower system to prevent puddles from turning into gore pits.

It seems like the actual bug in this report is thoroughly covered by 0000296, so I'm closing it as a duplicate.
