Aging Warehouses

Overbuild your warehouses to save space in your cities, get rid of outdated building models, and adapt to your city no longer having a certain type of rural improvement due to urban sprawl. Features: Warehouses on land (i.e. all Warehouse buildings except for the Fishing Quay) are no longer ageless and can be overbuilt. Warehouse building yields are automatically unlocked for all cities in the next age, meaning all cities get the Granary's bonus of +1 Food to Farms in the Exploration and Modern ages even if these cities no longer have a Granary (in those ages, the bonuses get attached to the Palace and City Hall). Fishing Quay has been excluded because a) it has special functionality even in later ages, especially regarding the economic legacies and b) space on water tiles isn't as contested for.
