You can't rank up from merchant in this mod because it is required that you have a graveyard, a graveyard needs a tombstone. but the mod only has HEADstones. none of which work for the description and I have tried them all. Love the mod wish mca was always like this otherwise tho! also 2 of my villagers randomly went missing but their apparently not dead which was kinda weird. Id love if the villagers gave you a headstone or something from them in your inventory when they died because that would be amazing.
