0002488: Hot items exposed to rain generate excessive amounts of steam
I embarked on a site with a surface volcano, and created a lava flow across a portion of the map. A block of a magma-safe stone (orthoclase) was left in the channel and became surrounded my hot magma at a depth of typically 1/7 or 2/7

When it started to rain, the block became a source of a never-ending steam cloud. I came to the conclusion that this was because it was being repeatedly given a water covering from the rain that would instantly boil.
Embark on a map with a surface volcano and a biome with rain. Create a block of magma-proof rock, and place it in a lava flow.

Why is this a bug? Is it the inconsistency between the block producing steam and the lava not producing steam?

It's the amount of steam. It appears more like a geyser on the screen - when I first saw it I though I had tapped into some cool feature!

Sadly I deleted the save in a drunken ragequit, so I don't have it - I could try and reproduce. If you saw it on screen you'd agree it's a bug. Needs some sort of check on the temperature before trying to create the water coating.

You probably don't need a save since I've reproduced this in the arena. Its slightly random in that you have to wait in adventure mode for it to rain and objects that are otherwise covered in magma will start steaming like a geyser. I think it happens to stuff which have a z-level or more of 7/7 magma between them and open space.

It also happens to magmamen and pyrozombies who get caught in the rain I believe.
