Anno 117: Pax Romana — Patch 1.5.1

Patch 1.5.1 addresses multiple gameplay and stability issues in Anno 117: Pax Romana, including restoring ship trade route persistence and names when moving between provinces. Amphitheatre Events can now run simultaneously on different islands, and trade route filter options have been fixed for better usability. Several fixes were made for DLC 01, such as enabling offline content, correcting festival appearances, adjusting difficulty settings, and resolving multiplayer questline and volcano eruption issues. Additional improvements include resolving crashes when switching graphics settings, fixing unit deselection problems, correcting blueprint aqueduct income bugs, and patching various multiplayer errors and user interface problems, especially for gamepad controls.
