i havent updated the mod so new buildings from 1.3 are not affected

Despot's Palace in Athens require Eastern Roman heritage.

I suggest change the name that contains Holy Sites, so its simple to find it.

Important Mod that no ones see. Thank you.

no because the changes have to be implemented individually on the buildings so it is not compatible with mods that remove buildings i assume (and if a mod add buildings they wont be affected)

is this compatible with AGOT?

Brilliant idea, always bugged me that I couldn't use the Christian holy sites as a Viking unless I converted or add Christian Syncretism to my religion.
