SYSTEMATIC ISSUE ISOLATION
BINARY SEARCH METHOD
Most efficient method for large mod lists:
- 1. Disable half of your mods
- 2. Test if the issue persists
- 3. If issue gone, it's in the disabled half
- 4. If issue persists, it's in the enabled half
- 5. Repeat with the problematic half
- 6. Continue until you isolate the specific mod
CATEGORY-BASED ISOLATION
Disable entire categories to narrow down the source:
DISABLE BY TYPE
- • All weapon mods
- • All visual mods
- • All quest mods
- • All settlement mods
DISABLE BY IMPACT
- • Script-heavy mods
- • Performance-intensive mods
- • Recently added mods
- • Beta/experimental mods

THE ANALYSIS
- • Modern Firearms adds weapons with custom stats
- • Weapon Balance Redux overrides all weapon stats
- • See Through Scopes modifies scope records
- • All three mods edit leveled lists differently
THE SOLUTION
1. Modern Firearms (base weapons)
2. See Through Scopes (scope modifications)
3. Weapon Balance Redux (stat changes)
4. Custom patch forwarding MF weapons to WBR
5. Bashed patch for leveled lists
CASE STUDY 2: SETTLEMENT SYSTEM BREAKDOWN
THE PROBLEM
User combined Sim Settlements 2, Homemaker, Place Everywhere, and Scrap Everything. Building menu became unstable, objects disappeared, and settlements crashed the game.
THE ANALYSIS
- • Sim Settlements 2 completely overhauls settlement system
- • Homemaker adds objects to vanilla categories
- • Place Everywhere removes settlement boundaries
- • Scrap Everything modifies precombined objects
- • Script conflicts between automation and manual building
THE SOLUTION
Track A: Sim Settlements 2 + compatible add-ons
Track B: Homemaker + Place Everywhere + manual building
• Cannot combine automated and manual systems
• Use SS2 integration patches for compatible objects
• Limit Scrap Everything to specific settlements
CASE STUDY 3: VISUAL OVERHAUL PERFORMANCE CRISIS
THE PROBLEM
