I have noticed following beaviour during playing build 136737.
I hid from a pack of wolves inside one of those civilian barracks buildings (if you don't know what i mean, watch the video) near Krasnostav Airfield (NE of it, the compund in the forrest).
Beeing traped i decided to open the door to let in single wolves, but noticed they wouldn't come after i opened the door. When i went to see why, i have noticed, that the wolves refuse to go through the main door inside the building, and that, even if they jumped through it, they would try to go out, instead of attacking me (only when i was in direct attack range).
Lucky for me, they dindn't do any damage in that version.
I suggest you watch the video, and see yourself.
