I haven't been playing for very long, so you can imagine my excitement when I finally got a good start in the beginning.
So there I was, just beginning to get my fortress off the ground, when I start getting notifications about my dwarfs having their work interrupted. I feared it to be something bad, bad enough to endanger the entire livelihood of the fort. I pictured Boatmurdered.
I zoomed to the location to see... a deer.
I figured it wouldn't be much of a problem and unpaused the game, choosing to see how this would play out. It was just a deer, right?
This deer single-handedly stopped almost all production in my fort because it rampaged through the only hall connecting the surface to my Dwarf's workshops. It stopped them from working, pushing them aside as it rushed through the halls, and kicked my Dwarf's teeth out for crying out loud. Blood was strewn across the halls.
Quickly seeing the damage done, I rallied the dwarfs into a single squad and sent them into glorious battle, most without even a weapon.
They chased this deer for a good two minutes up and down the halls, punching, kicking, and wrestling until this thing finally collapsed from a damaged lung.
My only decent carpenter Dwarf now has two broken feet and no teeth along with other miscellaneous wounds shared by the other Dwarfs, and it's taken so long for them to kill it that they are behind on the harvest and don't have nearly enough space for the migrants flooding through.
I hate this game.
