Well, I figured out one part of what was going one. I had recently
refactored one of the "hooks" I was using for identifying assemblies
in which fluent mappings were happening. Resolved that one.
Still, however, am faced with a non-trivial subclass map issue, B
connected to A, C connected to B. It seems like Fluent and/or
NHibernate want the subclass to be at most two levels deep, but I
could be wrong.
