Mate your mod is pretty great but i get errors on worldgen in the errorlog.txt I decided to look around and it SEEMS! like you made some mistakes placing certain things at the proper posistions in your mod files. This is entirely based on my own modding experience and I might be mistaken but for instance, your taiga trolls casts are not properly set. I have had similair issues and decided to do the following; you might want to look at how the creatures in creatures expanded (17.x) are setup, I used those as a base template and made my own races from according to how that certain mod author setup his mod (Sry dude forgot your name.) if you do this you are sure to make fresh new races without any difficulties.
Errorlog, With the naga and Girtablilu removed, i did so because they din't take my fancy so my excuses if I missed any bugs.
[Impoverished Word Selector <---- forgot if this a normal error or not but it dousnt show up for me after I restructured your creature file for the offending races.
