Naval Overhaul, AI Global Config, and Autosave

This update focuses on a major naval overhaul, AI global configuration upgrades, and the new autosave system.

Quick controls:

• Press 1, 2, 3, 4, 5 to switch different map modes.

Naval and trade updates:

• Added an independent navy and merchant-ship system; fixed infinite navy production and related lag.

• Navy count is now controlled by dynamic port quotas (default: 1 navy per 3 ports).

• Added port occupation/reclaim and blockade logic, including blockade markers.

• Navies can now engage and sink enemy merchant ships in sea battles, with rebuild cooldowns.

• Land armies now prefer embarking/disembarking via ports on long cross-sea routes.

• Navy, army, and merchant units now prefer moving along established sea routes.

• Land battles in blockaded port provinces now deal 2x damage.

UI and interaction:

• Added a new navy information panel.

• Added a dedicated merchant-ship information panel.

AI global configuration (Edit Panel -> Global Commands):

• Merged scattered AI toggles into one unified global configuration entry.

• Supports unified control for diplomacy, rebellions, vassals, alliances, ally support, auto-abandon isolated land, civil war, and family rebellion behavior.

• Added configurable minimum intervals for province rebellions, family rebellions, civil wars, and starting new wars.

• Added dual reset actions: Reset AI Options and Reset AI Parameters.

• Rebellion and war interval values now apply only on confirm to avoid accidental immediate changes.

Autosave and technical updates:

• Added autosave toggle and interval settings (5-60 minutes).

• Added a 5-second autosave countdown with ESC cancel support.

• Autosave must be enabled in Map Editing -> Global Commands.

• Migrated army and navy icons to the SVG pipeline with unified fill and stroke visibility controls.

• Fixed map-switch army coroutine out-of-range issues and rebel-removal crash risks.

• Improved pooling, batching, and route update performance for naval systems.

• Optimized feature-cluster and province-mapping rebuild flow after terrain edits.

2026 roadmap:

Our 2026 updates will focus on richer map detail and system depth, including second-level administrative divisions, road trade and supply lines, a rebuilt economy and population system, military branches and national strategy mechanics, and more extensible mod support based on Puerts scripts.

The next major update planned for June is expected to deliver these features. As systems keep expanding, the UI has become increasingly crowded, so we plan a full UI redesign after these systems are completed.

We hope to bring everyone an even more vivid Fantasy Map Simulator experience.
