Hello, I wanted to play with the game files to see what I can change, so far I have managed to add the race "Polymorph" that would have all kind of special attributes from other races , and apparently it required to modify multiple game files.

I now want to add an age category "elderly" to the initial "teen, adult, mature" but it does not seem simple to do so without triggering an error message somewhere (or weird description).
Can someone point me to the files I need to modify to add this new "elderly" category?

To be more precise: I've added a bunch of stuff, but I cannot resolve this error (game runs fine but terminal goes awry when interacting with an "elderly" character):

SCRIPT ERROR: build_attrs_for_char: Invalid get index 'elderly' (on base: 'Dictionary').           At: res://src/core/globals.gd:390
