So, playing the current version ive noticed some.. considerable changes to how creatures interact with each other.
Dwarves seem really ballsy at times. When i breached the caverns, they (as in civvies) ripped a giant olm to pieces and ganged on a cave croc. No casualties in either incident. I guess that works for me, but is really uncanny considering how such encounters went in the past and their fear of everything in the newest versions.
The most bizzare thing ive encountered thoguh was.. a GCS in my dining hall. I only noticed because a hen got killed by him. Considering there was quite a trip between said place and the cavern entrance, I was quite suprised to say the leasts, especially since 10 legendary swordwarves were guarding the entrance.
Now the weirdest part, it didnt cause cancelation spam at all. Dwarves ignored him and it ignored them. It killed a hen, a duck and a dog. Perhaps Snokugusslax was different than the rest of their kind and seeked admission to the fortress, killing the animals to show that he is a superior breed.
We won't know since Tadlibash, a resident dog (in name only), who made a name for himself happily chasing and disemboweling each and every animal that so much as looked at it the wrong way (jaguars, buffalo, the usual), decided to literally shred the cave spiders cephalothorax into pieces.
I dont know what is happening in this fort, but I imagine someone might be live testing steroids.
On a slighty related note, has deconstructing stairs changed? If you wanted to deconstruct a whole level of them from below, dwarves would do just that. Now, the first such set was deconstructed normally, but the second one yielded two dwarves who decided to test out the new falling damage.
