Something very odd is happening with loyalty and factions in my fortress.
I caught me a dingo man necromancer ranger (who in my mind has a thick bushwhacker 'straya accent) but he was displaying some odd reactions. I locked him with view of some corpses, and a dog to put him in combat stance, but the dog didn't alarm him, neither did exposure to wildlife (and that alarms everyone but an elf i thought). Finally i locked him in the same room as an ogre i caught from a siege, along with a kitten that belonged to my fortress. None of them attacked the others. What the heck!
Finally i did some save-scumming, i let him wander throughout the fortress. One iteration, he hit the main thoroughfare and everyone left him be, he wandered a little bit through the fortress till he walked into the entrance weapon traps and prompted redecorated the lobby in red and green. Another iteration, he wandered happily through a squad, who paid him absolutely no heed, didn't run to greet him or act hostile until some switch went off in their brains and they hacked him to pieces.
Theres been some other wierd stuff, like i dropped a wild weasel in front of my firing squad, who merrily ignored it till i ordered them to shoot it, when up till now i've never seen military dwarves have anything but a kill-on-sight policy with wildlife. I am a very confused Overseer right now
