Racial demographics not saving after being edited

[cyrixdx4]

Describe the bug

Alter the race % to any value after initial generation. % does not change nor does the primary race if selected to be greater than initial race.

To Reproduce (bugs MUST be replicable)

1. Generate town
2. Change % of race to be greater/lesser. Encountered this with trying to make dwarves the dominant race
3. Save Changes
4. See that race is not the larger % even though selected.
5. Edit town again to alter %.
6. Save Changes
7. Initial race that was higher % is still larger in number.
