DeadAir Economy Overhaul — DA Classic v2. 0. 2 (Localization Fix Pass)
Community-maintained continuation of DeadAir Economy Overhaul by DeadAirRT under the GPL-3. 0 licence he granted at retirement in September 2025. Full economy rebalance intact, tested on X4 9. 0 release.
Companion mod: DeadAir Scripts DA Classic v2. 0. 2 — install both for full DA experience.
NEW in v2. 0. 2 — Localization fix pass
A QA sweep over the 12-language localization (added in v2. 0. 1): completed 4 missing ware-detail entries for full parity with the base and verified key-parity, %s placeholder, and template-ref integrity across all 12 languages. No code or gameplay changes.
Localization — 12 languages
Storefront strings + full runtime UI (18 entries) now translated by native speakers into all 12 languages X4 supports:
-
[]Русский (RU)[/]
[]Français (FR)[/]
[]Español (ES)[/]
[]Italiano (IT)[/]
[]Čeština (CZ)[/]
[]English UK[/]
[]Polski (PL)[/]
[]Deutsch (DE)[/]
[]Português (Brasil) (PT-BR)[/]
[]日本語 (JA)[/]
[]한국어 (KO)[/]
[]简体中文 (ZH-CN)[/]
[]繁體中文 (ZH-TW)[/]
Translations reviewed via LLM native-speaker pass + adversarial verification for translation quality, terminology consistency, and template ref preservation.
What DA Eco does
Rebalance of pricing, production, and general economy on top of vanilla X4:
-
[]Storage boost fix (200k+ ConstructionPlan errors → 0) — per-station L-container boost wrapped in a `hasfixedconstruction=false` guard, silently skipping vanilla fixed prefab plans. 75 non-factory stations still get the boost. Log spam: ~44 MB → ~4. 8 MB per session.[/]
[]God defaults 40 production / 20 storage per station (was vanilla 5/10). Bigger stations at game generation → fewer total factories needed for the same output.[/]
[]Xenon energycells quota tightened — replaces vanilla `<quota galaxy="12" cluster="3"/>` with `<quota galaxy="12" cluster="1"/>` + adds `<sunlight min="0. 5"/>` gate. Standalone Xenon solar plants drop from ~12 to ~4 galaxy-wide, only in sunny sectors.[/]
[]Runtime sunlight filter for Xenon expansion — patches `factiongoal_hold_space.xml`: when Xenon tries to place a low-tech factory via runtime expansion, energycells is stripped from the candidate list if the target sector's sunlight < 0. 5.[/]
[]EventDynamicNewsOutput null-safe — 10 error hits per session eliminated.[/]
