0000142: Volcanoes' left sides can protrude buggily above slopes -- height check not symmetrical?

Confirmed on two worldgens and two fortresses with a volcano.

Confirmed. Also, the magma chamber stays vertical even when the mountain leans, making said chamber stick out of the ground like a giant obsidian tube filled with magma

I would also like to add that in the few worlds I have generated (3 smaller, 1 medium), each world had only 1 single visible volcano in the entire world.

Confirmed, from Z level 54 to z level 156 I have a nice tall lava pipe, which holds exactly the same shape at every single level. It may even extend further down but some sort of obstruction I can't actually see interrupts my view of the pipe at the bottom 20 levels or so.

The obstruction is the magma sea.

Confirmed. For some fun before it (likely) gets fixed: puncture the tube. Flood the world with magma.

my first guess would be that it is the magma sea yes, but since I didn't go down there to look and reveal was crashing on me, I didn't say for sure.

What was funny to me was that after 30 or so level down, I stopped being able to see the walls of the pipe, only the magma.

I think I have figured out the cause of the volcano tubes that extend out of the ground like a straw!

Volcanoes whose rightmost edge is at the TOP of the mountain extend above ground, whereas volcanoes whose rightmost edge is at the bottom of a slope (mostly) correctly create a "pit" on the rest of the upward slope.

My guess is that when the volcano gets placed, somewhere the algorithm mistakenly uses the x-coordinate rather than the z-coordinate to determine how deep the volcano tube should be.

I hope this gets fixed - it is a real deterrent from starting on volcanoes for reals (that is to say, I cannot resist puncturing the tube and watching the forest flood with red goo).

On a related note, it seems the actual number of volcanoes never goes over the "minimum volcanoes" value when creating the world, so if you want more than 1 you have to turn that value up.

The tube being the same shape all the way down makes tapping it to actually use for anything other than hot, hot death rather difficult.

Sadly, this bug is still around. Makes life much harder if you want to work with magma.

Is the issue you described at 0000142:0002579 still present?

This bug may be related to why this embark is so weird. The volcano just rises straight up like a tube and has a shear cliff face on the west. The embark location of the Dwarves on this map is hilarious!

The volcano tube is the same shape the whole way down.
