Sorry if this has been posted already, couldn't find anything with the search function and don't feel like sifting through 18 pages right now.
When installing on the enhanced editions only the true class ranger gets d8 hit dice, the rest keep the d10. Looking at HPCLASS.2DA it seems every kit has been assigned its own "hp class", as opposed to the original game where it was set by the base class. I assume they did this purely to accommodate the dwarven defender and dragon disciple kits (and mod kits too I guess?).
For now I've just gone and changed the values for the ranger kits manually myself (no coder otherwise I'd have added to the .tpa file myself).
On that note, R/C multi will most likely need to have its hp table changed too yeah?
