Outdoor caves?

As Kyllothan, a dark elf ranger, caverndweller explorer, Village Scout, I had a number of clashes with a Valtaire and Enhal in the Tunnel below the Destructor in the Village. I noticed I did not get a single shadowstride or rebounding strike, but plenty of dodges. I seem to average about 1 rebounding per 30 to 40% of dodged attacks in a cave. Trying to figure out if this is by design, or a bug. Two logs for you, first a log of our fight, then a log of the room descs. I believe it is tied to the room being outdoors (I later put the indoor/outdoor line in my prompt to help determine this). From the room descriptions, it definitely seems indoors. **SNIPPED**
