Can't you open the original map in MapView, then create a bare map, then select the stuff you want from the original, copy it and paste it in the new map? I thought MapView supported stuff like this.
Era=CLASSICAL should be Era=ERA_CLASSICAL
also,
Speed=NONE should be Speed=GAMESPEED_NORMAL
I fixed those two things and it worked.
there should also be a indo-greek kingdom.
Is this... dead?
I would be really sad if it were.
I'd love to help with this. Unfortunately, XML is my current modding limit
