History log overhaul and giant-map optimizations
Fantasy Map Simulator Patch Notes — October 29, 2025
Aggregated from Steam, cross-tracked with Battle.net coverage on GamePatchNote.
The history log panel has been rebuilt so you can jump to any year and turn pages forward or backward with precision.
Improvements:
Heightmap and biome painting on huge maps now runs much smoother, eliminating the heavy stutter that used to happen after finishing a pass.
Sea routes render faster by merging their meshes to cut draw calls.
Bug fixes:
Fixed some provinces inheriting tiles from neighboring provinces after generation.
Fixed rebel wars continuously spawning new armies.
Fixed the family tree panel occasionally opening with no characters.
Fixed national borders failing to refresh after rivers were cleared.
Fixed the Translate Map command under Map Editing -> Global Commands so it now completes successfully.
