I had a wonderful fortress going, fended off every siege, fabulously wealthy, etc.
My prior diagnostician had died due to circumstances that I forget. Having a fresh one I picked a dwarf best for the role. I figured I'd best train him up.
There was a back entrance for the wagons filled with trade goods to come into the fortress attached to a bridge. Now this little bridge was simple, over a 2 Z pit and triggered by a lever, it was right next to the hospital and had a ramp up on the far side.
I'm sure you can see where this is going, but I loaded it up with Dwarves... short useless ones that can't work yet, about 10 of them. My plan was to pull the trigger and let the doctor train up on their bruises... Apparently Dwarven children are the polar opposite of cats, as when dropped any amount of distance a fair number go seem to go bottom up. If memory serves there were numerous broken arms, broken legs and amazingly enough 2 broken skulls/brains, and of course, plenty of bruises.
Coincidentally I had just executed all of the useless pets I could to save on frame-rate. A story to itself I made an execution hatch far above my vast trapped bridge entrance over a 10 deep pit. upon filling it with the various pets they all seemed to just cling to the edges and not plummet when I opened the trapdoor... So I opted for a spike/lever solution instead, this worked much better.
Needless to say the fort rapidly devolved into a tantrum spiral *Insert facepalm*, the kicker on this little story is that I had accepted becoming the capital earlier in the year and the queen arrived during the worst of this fighting... For science sake I can state that she did not seem even the remotest perturbed by this as she walked through the halls of fighting Dwarves, just as stately and composed as she could be, alongside children whom's legs were ripped off and then used to beat to death the legless engraver (a profession I cannot help but always give to the dwarf with the least limbs).
I saw the end of this fortress (when I see a loss of around 85% of the population in one go I tend to abandon) and proceeded to load the queen into the first pet execution drop. She did not cling to the walls. As far as I could tell the dwarves were neither moved to tantrum harder, nor stop.
I caught much of it on video. I was going to make a youtube video of it but got bored, I'm sure I have the footage around somewhere.
