Indian Cultures get a new cultural building, only available outside the Indian subcontinent; a Rajput in Norway can no longer take his Elephants with him----- Y can not see it in 3.3.3

It's working fine for me. You're only checking provinces that have an Indian culture and are outside the Indian subcontinent, right? The new Indian culture building works the same way as normal cultural buildings; the local culture, not ruler one, is what determines if it can be built.
