Build v159.6 of Mindustry is now available - the next bugfix release following v159.5.

Mindustry is a mix of factory-building simulation and tower defense, where resources move along conveyor belts while bases are defended against waves of enemies.

The update mainly fixes issues with music rules, the Littoral Shipyard, and generated icons.

• Fixed custom music rules not updating when editing rules before playing a map
• Fixed Littoral Shipyard not having waves
• Fixed icons not generating properly in data patch content
• Added support for loading mod assets in map music rules
