February 2026 — TerraFirmaGreg-Team/Modpack-Modern delivered a major system-wide energy and modpack refresh, combining a comprehensive overhaul of the fission energy pipeline with targeted stability fixes and internal refactoring to improve maintainability and future iteration velocity. Key outcomes include a complete Fission energy system overhaul: balance refinements across early- and mid-game power, expanded energy generation options, new quests, and UI/texture enhancements; accompanying updates to existing components and recipes (including fission rod recycling, texture updates, and quest updates) to deliver more coherent progression and visuals. EV enhancements were introduced with laser hatches, new components, and balancing tweaks to machine casings outputs, expanding end-user capabilities and automation potential. GTCEu modpack adjustments and internal refactoring removed gtceuterminal recipes and reworked machine registration to support fluid import/export, simplifying maintenance and enabling smoother future feature blocks. Major bug fixes included resolving the nuclear line hardlock, aligning LSA/mk2 placement and AE2-related recipe changes, hiding items from ExtendedAE where necessary, and reintroducing tooltips for the Heat Battery to ensure clear user guidance. A dedicated changelog update captured these fixes and changes for release visibility. Overall impact and business value: stronger gameplay balance and progression, richer player experience with updated textures and quests, reduced risk of feature conflicts through refactoring, and improved maintainability for faster future iterations. The February work aligns with roadmap priorities for expanded energy and automation capabilities while keeping the pack stable for ongoing use and release readiness.
