[race: human] Acolyte Gold gathering not working

[jintlox]

Made the worker Human to have repair building possible, but Blighted Gold mine stopped working. How would I go about fixing this (without creating additional units)?
I also intend to use blighted gold mine ability for that faction

i'm pretty sure some of those abilities are hardcoded to race, thus you need to make the worker belong to the undead
