Added
Global Effectiveness Guard: Added a robust wrapper in Hotfixes.rb to prevent ArgumentError crashes when nil types are passed to Effectiveness.calculate.
Matchup Improvement Logic: AI now compares the candidate Pokemon's score against the current Pokemon's score. This avoids switching for marginal gains or equal stats.
Fixed
Infinite Switch Loop: Resolved the issue where the opponent would endlessly switch between two similar Pokemon (e.g., Cloyster and Lapras) by requiring a significant matchup improvement to trigger a switch.
Double Battle Crash: Fixed NoMethodError: undefined method 'ai_skill_level' by correctly passing the skill level from the AI Core.
Switch Logic Crash: Fixed NoMethodError: undefined method 'pbCalcTypeMod' by migrating to the Effectiveness system.
Spread Move Crash: Fixed NoMethodError: undefined method 'targets_all?' in Doubles_Coordination.rb for v21.1 compatibility.
Move Property Crash: Fixed NoMethodError: undefined method 'base_damage' for non-damaging move classes by adding robust property check fallbacks.
Stalemate Logic: Improved detection for offensive immunities. AI will no longer stay in battle just because it is immune to the opponent if it cannot deal damage in return.
Improved
Type Guarding: Added strict nil-checks for move types throughout Switch_Intelligence.rb.
Performance: Caching and error handling improvements in the Core AI loop.
