Knowledge base (~) odd behaviour?

[MKula]

Hi all,
I'm a rare poster, but I noticed something odd in the knowledge base for monsters and this seemed like the best place to post it.

I play around with the monster.txt file quite a lot to add/delete and try out different monster types. Recently, I've been playing around with the monster_base.txt file (now that it exists!) and I noticed that the monster memory (i.e. ~ --> d) doesn't really link to monster_base.txt.

Two examples:
I renamed "icky things" as "insectoids", yet icky things remain in the monster memory and insectoids do not.
I set townsfolk to "h" since I wanted to free up "t", and I created a new monster type called "totem" with a "t". I then created 3-4 new totem monsters in the monster.txt file with the totem monster_base... and they appear in the monster memory under "Men". Furthermore, it appears that "Men" refers to "Townsfolk"... but they're not listed that way anywhere?

Can someone help clarify this for me? Is what I mention above a feature or a bug?

Thanks in advance!
