Age of Production: Legacy

Requires Factorio 2.1.24 or later.

This fork retains the manufacturing and scrubbing content of Age of Production 1.0.11 on Factorio 2.1.24.

It includes the original smeltery, biochemical and electromechanic facilities, advanced agriculture and metallurgy, air scrubbing, wastewater treatment, and the associated machines, recipes and technologies. Their internal prototype names, footprints, fluid ports, crafting costs and research costs are retained. The compatibility category declarations are limited to the original 2.0 categories that these retained machines actually use.

Current Age of Production and Age of Production Classic have removed or reworked parts of these older chains. This fork preserves that older factory content. It is a separate mod and cannot be enabled alongside either original overhaul because their prototype names overlap. Space Age and PlanetsLib are required.

Existing factories

For a factory using Age of Production 1.0.11, replace that mod with this fork and retain the factory's startup settings. The retained release is data-only, with no runtime storage to transfer. Factorio's native migration ownership links this fork to the original mod identity. Entity, item, recipe and technology identities remain the same. The engine's own 2.1 recipe migrations still apply.

Validation

Headless Factorio 2.1.24 checks loaded an existing 1.0.11 factory under the new mod identity, completed two matching 1,200-tick consistency runs, saved through the native paused server, and completed two matching 1,200-tick runs after reloading that converted save.

Foundry Restructuring compatibility accepts both the original mod and Foundry Restructuring: Updated, retaining the original electromechanics recipe categories.
