PROBLEM: Same question being asked twice instead of progressing - Question 1 answered → AI responds → Question 1 asked again (not Question 2) ROOT CAUSE: currentQuestionIndex not being incremented after answer - askNextQuestion() was using same index repeatedly SOLUTION: - Added currentQuestionIndex++ before askNextQuestion() calls - Fixed both success and fallback code paths - Now properly progresses: Q1 → Answer → AI Response → Q2 FLOW NOW: 1) Fish live where? → 'in water' → AI validates → 2) Next question NOT: 1) Fish live where? → 'in water' → AI validates → 1) Fish live where?
