I decided to try build a bath house and after working out how ponds work properly, designated one to be built in a bathroom. Just  noticed that whoever was going to fill it up decided blood is a better material, and somehow injured himself and bled into it. This gave me two thoughts. 1) Dwarves can hurt themselves doing ANYTHING. 2) Is a bath  made of blood viable? perhaps with a some water in it? Or will this either loop them constantly trying to clean themselves, or just not use it?

edit: They seem to be seeking out blood SPECIFICALLY to fill the bath with, as I've just had giant jaguar blood deposited in it. No water at all so far, and several tiles of different dwarf blood exists in it now. Is this normal (for Dwarf Fortress)

It would be from an old wound, or someone else's blood.  Take some time to check their inventory.  Dwarves are disgustingly filthy, covered in blood, vomit, and mud.  As soon as they touch water it explodes in a vortex of filth.  This is intended behavior.

Yeah, blood is kinda buggy in DF at the moment... Quite often I'll have a dwarf die soon after embark, and years later when they're nothing more than bleached bones lying in a tomb somewhere, new migrants are still tracking a few litres of their blood around.

odd, the water was at most 1/7 on a single tile when it started, and its maybe 2 tiles of 1/7 now and theres blood EVERYWHERE in the pond, despite no water existing within several tiles.

Also, blood does seem to expand rapidly on contact with water.
I remember this one time I built a waterfall, it washed all the blood off my dwarves and then sort of... Created more, somehow. Like magic cordial!

I still fail to see why a blood filled bath house is wrong or not-dwarfy.

[Girlinhat]

Again.  This is intended behavior.

Oh, not wrong at all. As long as it carries out the intended function, I intend to do a lot of blood related "fun"
@girlinhat: Ah ok, just seemed weird the distance the blood was spreading from the water.  This will be very useful. Drowning invaders in a sea of blood has its merits.

[Girlinhat]

Try flowing water.  Contaminants actually flow upstream!  It's absurd!  When trying to dam up a river, I pumped water onto the ground so that I could manage to get some quick walls.  The bloodstains on the dirt started flowing towards my pumps!

[Spacespinner]

That can only have ended messily

[Girlinhat]

Actually, I recall it ending rather well.  The blood and vomit flowed upstream until suddenly hitting a tree and sticking to it like a magnet.  I cut down the tree, and it was all clean.  Except for the mud over THE ENTIRE MAP.

Isn't this a problem related to the way liquids are rounding up/down?

I can remember a post, where people said it was possible to create more liquids by simply splitting it up and merging it.
I forgot if that post was actually about Dwarf Fortress or not :p

good old integer math:

2.4 + 2.4 = 4.8

after rounding :

2+2 = 5.

This was a bug that was fixed many versions ago.  There was some unusual behavior with U-bends where it was possible to multiply water infinitely.

It is still possible to multiply water by using freeze/thaw cycles.  Any depth of water will freeze to make a solid wall of ice.  A solid wall of ice will melt to make 7/7 water.  Split that water into multiple tiles, freeze, thaw, and you have more water than you started with.  Not a roundoff error exactly, just a quirk of how DF handles water and ice.

The problem with contamination being multiplied by water seems to occur when a tile of water with contamination in it spreads into multiple other tiles - the contamination gets duplicated into each destination tile.

DFClean helps, but I wonder: Is this murder in the bath house? Did Urist McHolmes find traces?
