Most of July was still dominated by bringing up multiplayer for all the existing game functionality, this time focused on the train simulation. But now the bulk of the work is finally done, and the framework is in place to network any future features too. The jams seen in the demo also received a mitigation feature that foresees the future work on signals. And it looks like procedural building simulation as moved from "research project" to "actually may happen and be tied to a feature, not just for show".
