How can I heal my villagers?
Solution 1:
Just throw splash potions of instant health, that should do the trick.
Solution 2:
Currently the only NPCs that heal in the mod are Guards, who heal themselves by eating food.
Employing guards should keep hostile mobs off your other villagers, so that they shouldn't need healing anyway!
Solution 3:
I found this from one of the developers:
Regarding regen health.. I thought they healed themselves for 5 hp each night... If you always skip the night cycle though you will miss this
Considering I like to sleep a lot in the early game, this is probably my problem.
