Had one of most dreadful experiences in DF yet. I recently started digging to deeper cavern layers, and we found some natural downward passages, full of microcline and cobaltite, beautiful stones, and I haven't struck microcline before in this fort, so I had a new color for my building projects, neat!
But as I was mining the stone, I must have accidentally damage the slopes in the passages, so ten or so citizens were trapped in between the layers. Now that wouldn't be that big of a deal, I immediately designed a stair route next to the passage for the poor miners, but soon they started spamming job cancellations, sending the FPS to oblivion.
I had to use burrows to keep them from complaining and disabled all the hauling jobs they were attempting, somewhat improving the framerate. They managed to dig out the stairs before I went mad, and everything went back to normal, fortunately.
Also we managed to kill a necromancer, one less of those to worry about. Although, from what I gathered about our world there's a hey yeah lot of entities and governments lead by necromancer warlords, and only one was ever destroyed as it seems, and that was only because it was at war with different necromancer horde.
And another foul FB came, a mud blob with a tail, but it had to be spitting webs of course. So three of our soldiers were maimed terribly, but the healthcare took care of it, much to my surprise. The last time a web-spitting liquid blob crushed a half of my mace lord's body, she was in hospital for years, waiting for diagnosis.
