The lucky_dice mod rolls a 4, 5 or 6 for all of the Hearthlings’ attributes instead of the usual range of 16.
WARNING: If you open an existing game with this mod loaded it will reroll the attributes for all Hearthlings. If you do this by accident, close the game without saving and unload this mod.
To use this mod:

load the mod and open a saved game, it will reroll the attributes for all Hearthlings and replace any 1, 2, or 3 with a 4, 5, or 6.

save the game and unload the mod before carrying on playing.

when a new Hearthling arrives in town repeat the steps above to get 4, 5 or 6 for all attributes
I welcome all comments or suggestions for improving this mod. Would anyone like an unlucky_dice mod instead?
