How to get ancient ruins to spawn on saved maps?

[katherinebell]

Hello,
I haven’t really tried saving maps before, but there was one I wanted to replay with a different civilization. The problem is that ancient ruins don’t appear anywhere. After looking around, I saw mentions of a mod called “Random Goody Huts,” but I haven’t been able to find it.

I also tried installing a mod that increases the frequency of ruins, but it doesn’t seem to be working.
