Another question: Did you read anything about how it was in that area in Medieval Ages? Because from a current point of view cows as food on a map in India do not make that much sense.You are right. I'll be sure to update that before tomorrow. I thought I had included avoid_forest_zone but at a low value to make sure they found places, but it looks like there's nothing at all, so it's possible even avoid_forest_zone 1 gave me a generation with a missing gold. Thanks for the catch!
I don't know if maybe back then it was controlled by a culture that did consume cows.
