I'm not sure if I was cursed when you wished FUN! upon me, but it happened.
I got an infestation problem; giant gray langurs. The wiki says these furry bastards when it says they'll just kill a dwarf, loot its cloths and run away; these ones rushed into my fort, but now seem content to wander around it at random for some reason.
I tried to combat them with the militia, but... things happened. First, one of my milita managed to mine himself into a hole, then when he was activated dropped his pick, and I can't get him to pick it up again to dig him out. The other recruit rushed to engage the foe, entered a fey mood, and turned around, getting instakilled by the closes langur. Over all, 3 dwarves dead in one of the most vulnerable stages of a fortress's life, and I haven't got rid of the damn monkeys yet.
So the caravan arrives, sees the survivors being chased all over the map by these giant monkeys, and its soldiers help out by smashing any langur that comes near the merchants. I don't think we made a good impression - everyone was miserable, corpses were rotting in the hallway leading up to the depot, and our legendary miner was starving/dehydrating to death because nobody could be bothered to rescue him (we later got him free).
So we're saved, but now the tantrum spiral of year 1 begins.
I love this game.
