Only applies to roles who have just been bitten.
If the previous role of a Vampire had any abilities, they can use it again for one more night at any time.
E.G:
Bitten Mayor can reveal but lose the votes and whisper disability the next day.
Revealed Mayors who have been bitten retain the extra votes and whisper disability for one more day.
Bitten Vigilante can shoot once with no consequence.
Bitten Jailor can jail someone for one night, and even execute said person given that they haven't done so already.
