Vietnamese flag icon when choosing language for bot is wrong

Snatchbot flag icon for Vietnamese (https://snatchbot.me/img/flags_lang2/vi.png) is wrong. The official flag of Vietnam is a red flag with a yellow star in the middle.
I believe the current flag icon (a yellow eagle with U.S flag in the middle) is originally a logo used by the Third Republic of Vietnam, which is a government in exile. This oganization has acts of sabotage against current Vietnamese government.
Please correct this as it's not the official flag of Vietnam.
