Twitch Voice Lines

I was browsing a league wiki and i noticed that twitch has voice lines for buying potions and wards, but when i tried to trigger them ingame (yes i buy wards as an adc, shocking i know), twitch only used the voice lines for buying regular items, and not the specific potion and ward ones. Perhaps when normal sight wards were removed from shop (RIP) and control wards replaced pink wards, these voice lines became lost. Is this something that can be easily fixed? i love twitch as a character and i'd love to see these voice lines re-implemented
