Clickable fields are 'New Random Map', Climate buttos, 'Advanced' 'Load Heightmap', 'Edges:', and in Scenario Editor extra option 'Terrain Type: (Totaly flat)' Maybe for New Game also?
'Random seed:' eliminated can be set in console
'Snow line height:' description should be, 'Snow line:' and in button 'Above 2..13 tiles' Click arctic climate
Only when choosing 'arctic climate' the 'Snow line height:' should be visible
'Sea level:' should be changed in 'Sea Amount:'
Only when 'Totally Flat' is chosen 'Height:' Should be visible.
Only when 'Edges:, Manual' is chosen 'Freeform options' visible
Please change 'English(Original)' into 'English' (no space in button)
Clicking 'Load Hightmap' opens screen beside, and changes screen settings
All items are grouped in 'Map:' and 'Scenry:' the only one that does not fit completely is 'Town names' but for me no problem.
'Town names' was positioned below 'Towns' on purpose.
Advanced settings press + button top right corner.
