Dragon Trainer Trist voice bug

Last game I played with Dragon Trainer Tristana, some how her base attack and move quotes got thrown in after I bought an IE (I don't know if that's what created it or not) The Dragon Trainer Trist VO still played, but her base VO played much more frequently (Taunt, Dance, Joke and other sounds remained the same)

There was also another Tristana in the game using the Riot Girl skin which has her base VO (Don't know if that's helpful or not but there ya go :P)
