[R&F] Great Person Costs Help Needed

[skidmarkschu]

I have a mod that increases the costs for Great People. I play on Marathon and don't like seeing industrial age great people roaming around in the classical period. It worked prior to the update, but is no longer.

<GameInfo>
<Eras>
<Update>
<Where EraType="ERA_ANCIENT" />
<Set GreatPersonBaseCost="60" />
</Update>
<Update>
<Where EraType="ERA_CLASSICAL" />
<Set GreatPersonBaseCost="160" />
</Update>
.

and so on.

What can I do to get it working in this version?
