Hey, I just wanted to let you guys know about an issue that people are going to ask about.

You're using these tags

    <RequiresCityImprovements>1</RequiresCityImprovements>
    <RequiredImprovement>E_Earth_Shrine</RequiredImprovement>
    <RequiredImprovement>E_Air_Shrine</RequiredImprovement>
    <RequiredImprovement>E_Fire_Shrine</RequiredImprovement>
    <RequiredImprovement>E_Water_Shrine</RequiredImprovement>

for the new Tower of Souls and Temple of Essence buildings. In essence, they are meant to be buildable whenever you have a shard connected to the city as described in the buildings

<Description>The Tower of Souls increases mana produced by a city connected to a shard by 3.</Description>
<Description>Temples of Essence increase the mana produced by a city connected to a shard by 3.</Description>

However, this is NOT the functionality of those tags. Those tags demand that the improvement is built INSIDE CITY WALLS. It will NOT respond to shards that are just "connected" to the city.

I actually requested that this be changed a while back, for this very reason.
