My villagers keep dieing, monsters can break protected doors and what ever I try I can not get the protect-villagers flag to insert into a field.

It allow it with no errors, but on /ps info it will not be there.

Try the latest dev version.

The flag now sticks and protect villagers from players.
However villagers and doors are not protected from monsters.
