I wanted to test around with modding, to make a trait that only makes people with this rare trait a bit extra bigger, but the problem is with the new gene_height. I have no clue how you legendary code wizard made the traits, I can't seem to find any info online and can't figure it out ngl. If you can help, that'd be godly.
EDIT: Just to be clear, I tried the last hours to figure out how yours work, but to no avail. Won't show the physical changes in-game, only in the "Edit Appearance" menu under the heights.
