Quick Question regarding LastSword's Prophet Override

So I've been working on a mod of mine recently, attempting to utilize LastSword's HolyOverride.lua. I've gotten it to work for Missionary units in the past, but I stepped away from modding for months due to a hard drive crash and now that I'm back I can't seem to get the darn code to work.

As far as I can tell, I have everything set up correctly, with the proper civilization and unit ID. Whenever I should be spawning a unique Great Prophet, I'm still getting the generic one. Did a patch break the code or something?

Without posting the code, it's hard to guess what you might have done wrong.
