Help replacing religions

[spaceman98]

I am trying to replace the old religions with new ones, and I have encountered 2 major problems:
1: I have added a new technology, Sacrificial Cult, with which Druidism is founded, but I cannot add it to the Celtic starting technologies, I add it in Python, and nothing happens.
2: I have buttons for most of the new religions, and they appear in the civilopedia, but on the world map in cities, the old religion buttons still appear.

For the second one, did you modify the tga font file? That's where the map icons come from

Editing the TGA fixed problem 2!
