I understand that If I take a neutral reset territory then it will revert back to the default number of neutrals if I'm still holding it at the start of my next turn.
Question is what happens to a neutral reset territory if it's weakened but not taken?
For example if there's a neutral reset with 20 troops on it, I make an unsuccessful attack knocking it down to 3 and end my turn. Will this territory reset back to 20 at some point if no one else attacks it or does it just stay on 3 indefinitely?
