random map land settings?

[customer717]

Okay, so how do I change the % of different lands for a random map? If I change it in the text box and then close the window then open it again it goes back to the original value. If I change it and start the map, it does not take either as I set a 50% water to see if it was working and it didn't.

The manual seems to indicate that all I need to do is change the % values, but I can not get them to change. What am I missing?

Its not 50% water, its 50% river. Its the chance a river will appear. Select 100% wood, than the map size and you will see 100% woods.
