I'm getting a worldgen error creating a new world with the Archeologist enabled. If I disable the Archeologist the the world generates fine. Version is 1.5-154. Error:

java.lang.NoSuchMethodError: vazkii.arl.util.RotationHandler.getRotationFromFacing(Lnet/minecraft/util/EnumFacing;)Lnet/minecraft/util/Rotation;

Update ARL.
