Both have 50 % discount right now - and both require 8 WITH discount - Full price is 16 for sure. ( This is F15 and G15). F 15 ( I have yet used 0 lanterns on picture) on my G15 pic- I have 29/30
Both need 15, 50% discount is 8 as it is round upward not down! I have not paid anything so I have clear text. Still is is expensive, but not as much as some insane plots with a truck load of Explorers Permits (6 = 30 Expansion Permits for a single plot )!
