Summary (AI)

Patch 1.5.2 for Anno 117: Pax Romana addresses several gameplay and interface issues, including fixing DLC achievement visibility on Ubisoft Connect and resolving construction problems with Obsidian tiles groundplates. Improvements to the military AI prioritize villa capture over unit pursuit, and war declarations by rivals are now more strategically timed, with immediate surrender upon losing their first island to the Emperor. Specialist abilities have been adjusted for better balance, and quality-of-life changes include using CTRL/SHIFT to unload ship items without opening the trade menu. Multiplayer connectivity and campaign clarity have also been enhanced.

Tip: expand all for quick scanning.

Liable Ensurer: now applies its trade discounts correctly
Prima Quartienus: now applies its trade discounts correctly
Rivals will no longer declare war immediately upon early contact with the player / AI is now less aggressive in early-game
Rivals will now surrender immediately after their first island is conquered by the Emperor
Rivals properly take into consideration if a war declaration would result in a rebellion
The island capture progress is now not reset anymore if units move too far from the villa
The military AI now has a higher priority to capture the villa to take over the island instead of chasing units
Aolian Modist: also affects gold production of the Lyres production chain
Leave notes for yourself as reminders for later in your play-session or when you load your savegame a few days or weeks later and attach them to specific objects (e.g. ships).
