Restarts have now been disabled, so if you are nobled out of the world you will not be able to restart on w19. You will still be offered to move to Casual World.
The idea of morale is to help newer players, this is obviously not wanted in a world with less than 21 days to run. We'd like to push as close to 100% as possible and with a limited number of rebuilds left in this world it would be nice to not have to leave every noob with a bonfire.
With less than 3 full offensive troop rebuilds per village left in the world, it would certainly be nice to have each of them be effective, not having to throw 30 at a village just because it has a bonfire in it.
Kinda figured it would be removed when the 21 day countdown timer began...
