I like the new terrain types as well - I think that the body conditions for some of the terrains could be reviewed. I have a planet with 98.5% water coverage with the terrain type ‘cold steppe’ at about -22°, seems like the terrain type is not reflecting its aquatic nature
Also, I SM nuked Earth for a post-apocalyptic scenario, which changed the terrain type to volcanic plains - after all the radiation and dust was gone, the terrain type remained as Volcanic Plains - seems like it should have switched back to something more normal
