A compatibility and optimization patch mod designed specifically for the Regression Collection modlist.

This mod resolves various XML, cross-reference, and load-order issues on startup without altering any core gameplay mechanics.

What this mod fixes:


  • Progression: Education Patches: Ensures SkillBuildingRequirement nodes exist before compat patches run, preventing xpath failures for cooking, crafting, plants, intellectual, melee, and shooting skills.
  • Progression: Core & Warfare Patches: Prevents red errors caused by missing third-party mod definitions (like VWE_Longbow and Ferny_PlantPots) by injecting safe placeholders.
  • DankPyon & VFES Cross-References: Safely cleans up dangling and unresolved research prerequisites when certain mods/definitions are removed or renamed.
  • Davai's Sorted Categories compatibility: Prevents XML Extensions patch failures with Vanilla Genetics Expanded.
  • Alpha Mechs Biotech fixes: Resolves missing body part groups and apparel layer errors on mech master and siegebreaker helmets.
  • VGE Duplicate Categories Cleanup: Cleans up duplicate thingCategory (DankPyon_Milk, AnimalProductRaw) errors on VGeneticsE milks caused by load-order conflicts between Medieval Overhaul and other compatibility patches.
  • Gene Category Priorities: Resolves display priority conflicts between EBSG (RS_DarkArchite) and ReSplice (CoreFungal) gene categories.
  • DankPyon Turret Stuff Fix: Removes redundant costStuffCount from DankPyon turrets to prevent "madeFromStuff but stuff=null" errors during pawn generation (e.g. via SimpleLeadership).
  • VFE Pirates Deity & Ideo Fix: Adds the genuinely missing DeityTypeMakerKriminul RulePackDef for the Khanate culture, and augments NamerIdeoKriminul, NamerDeityKriminul, NamerFestivalKriminul, and LeaderTitleMaker_Kriminul with pirate-themed naming rules while preserving all base-game grammar functionality. Fixes grammar resolution failures for r_ideoAdjective, r_memberName, r_ritualName, and hyphenPrefix during world generation.
