0008183: Overflowing magma seas/pools after unretire or reclaim.
I unretired a fort, I discovered a magma sea (without message, just saw that it is there). The top layer of magma changed it depth constantly ranging from 5-7 after some time it would overflow and flood everything arround it. It doesn't stop.
All three caverns discovered. Magma sea located on layer three, connected to the also mostly discovered magma layer.
No tags attached.

Please upload a save (whole region folder) that demonstrates the magma sea overflowing to the DFFD ( http://dffd.wimbli.com/ [^] ) and post a link to it here.

Sorry for the late reply.

Unretire the only inhabited fort. Magma sea is located in the caverns, right upper corner. Sea will overflow in about 10 minutes, varying by FPS.

I've neither seen this happen in the provided save, not in a specifically designed test case that runs faster for me (in case that my low fps in the provided save is the culprit), but there's been more reports that I've seen, so there may be more variables at work. What OS do you, or anyone who experienced this, use? How long between retiring the fortress and unretiring it? Do you use any utilities?

Same happened to me. So still present in 40.13. Playing on Win7 64-bit
Steps to do that: Retire a fort with volcano, reclaim it.
Here is my save: http://dffd.wimbli.com/file.php?id=9800 [^]
The volcano used to be at the height of obsidian in the tube.
If you need more info, just ask!

edit: whoops, topic said unretire. I guess volcanos overflowing after reclaim is the same problem

While testing if a volcano would fill to a certain height, I somehow managed to stop the bug from triggering in some instances. The following save will have this bug a 42% of the time.

http://dffd.bay12games.com/file.php?id=12866 [^] [v0.43.05]

Before I started the construction, the bug occurred every time I unretired the fortress.

In the save I extended the volcano's height up to z = +50, I'm not sure if the building's height is stopping the bug or if it's something else. In the times the bug is triggered, the pipe will overflow the extended volcano.

I had this happen to my recent fortress which was retired and reclaimed on 44.09. After patching the entire magma pipe with dfhack liquids and letting the flooded magma cool I found my dwarves would not path over the flooded areas. It is almost as if the units think the magma is still there.

@Bobiloco: You'll need to enable temperature calculations if you want the previously-magma-flooded tiles to cool down. (0008391)

@Loci Thanks, I went looking for 'magma flood impassable' bugs and didn't find anything before posting but this makes sense!

I can at least say that building up walls around the pipe to contain the magma crabs seems to have triggered the slow eruption upon reclaim.
