Changelog

1.3.4 - 2026-07-29

Fixed loading multi-star saves created before outer hierarchy stars could own planets. Legacy plans now retain their original single-real-star planet topology, preventing core save data from being read with shifted planet IDs.

Fixed save loading when another galaxy-generation mod restores the selected gameplay-star count after Multi-Star Systems has expanded it into physical companion stars.
Multi-star save restoration now runs after compatible galaxy generators have completed their setup, and logs an explicit diagnostic when a .dsv file and its .moddsv sidecar do not belong together.

Added a compatibility warning for BulletTime, which may conflict with galaxy generation, stellar motion, or save loading.
Clarified the public compatibility notes.

Added compatibility with wandering planet III.
Reserved wandering-system star IDs outside the multi-star plan and prevented wandering anchors from consuming multi-star members.

Outer hierarchy stars can now generate and retain their own planets while remaining virtual for Dark Fog and Dyson-sphere ownership.
Double-binary systems now support an outer binary subsystem: its primary star owns planets, and its companion remains planetless.
Planet-owning outer stars remain directly selectable, reachable, and synchronized while their stellar hierarchy moves.

Reduced the default stellar orbit multiplier from 3600x to 1800x. Existing untouched 3600x settings migrate automatically.
Guaranteed a visible O-star or blue-giant virtual companion in each new galaxy without increasing the special-system rate.
Kept hierarchical massive outer stars virtual and placed them outside the real star's outermost planetary orbit; inner binaries remain compact.
Restored multi-star relationship text inside the star-detail panel, reserving vertical space so it no longer overlaps resource entries.

Raised the default stellar orbit speed from 20x to 3600x and migrated untouched legacy default settings so binary motion is immediately visible.
New galaxies now treat the selected star count as the number of planet-owning stars; a default 64-star galaxy contains exactly 64 real or single stars plus any required virtual companions.
Guaranteed at least one O star in every newly generated galaxy and separated white dwarfs from the neutron-star/black-hole compact-object binary branch.
Added inverse-square companion-star fill lighting on local planets. It is capped at 35% of the primary light so an opposite companion can produce twilight-level nights without full daytime brightness.
Moved multi-star relationship text to a dedicated side area of the star-detail panel to avoid resource-list overlap.

Reserved primary orbit slots 1 through 5 for every real star in newly generated multi-star systems; all direct planets now begin at slot 6.
Expanded each real multi-star system's maximum stellar diameter to 3.0-5.5 times the real star's theoretical first-orbit diameter.
Added separately randomized 1.0-5.0 factors for virtual-only nested subsystems, while keeping every hierarchy inside its real system's maximum diameter.
Added save-layout versioning so existing 1.0.x multi-star saves retain their original spacing and remain loadable.
Fixed multi-star plans being discarded during save loading or new-game initialization, which could reset stars to normal galaxy positions.
Added multi-star relationship text to the star-detail panel, including nested binary and four-star relationships.
Synchronize real-star planet poses immediately before star or planet arrival so sandbox direct travel uses current multi-star coordinates.

Fixed Wrong version of unigen algorithm! during galaxy preview and new-game creation.
Stopped using GameDesc.galaxyAlgo as a mod marker; the vanilla algorithm version is now preserved unchanged.
New games generate deterministic plans directly, while existing saves are recognized exclusively through matching DSPModSave data.

Fixed Harmony argument binding for Dyson editor star selection, which prevented version 1.0.0 from initializing in game.
Changed all single-star redirection patches to positional argument binding so original parameter names cannot break initialization.

Added deterministic two- through six-star system generation.
Added binary, triangle, hierarchical triple, square, double-binary, hierarchical four-star, pentagon, and hexagon layouts.
Added the requested 30% square, 30% double-binary, and 40% triple-plus-massive four-star distribution.
Added exactly one real star per system and suppression of planets, factories, Dark Fog, asteroid belts, and Dyson spheres on virtual stars.
Added direct-binary luminosity combination for Dyson spheres.
Added guaranteed special-star generation and approximately 50% special multi-star systems.
Added fast visible inner-binary motion plus moving outer stars and binary barycenters.
Added next-frame planet interpolation correction for moving real stars.
Added deterministic save serialization, navigation redirection, tests, and game-assembly patch validation.
