Uncredited kills (mobs other players killed that you never engaged) passed px,py=nil to LearnNPC, whose GetPlayerCoords fallback stored YOUR position as the mob's spawn and incremented the kill count. Gate spawn recording (LearnNPC + _StoreGuidSpawnEvidence) on a captured position, so only credited kills with a real position store a spawn. Bystander kills no longer pollute coordinates or inflate counts.
