The fortress accepts the farm command, but seems to have some troubles.

HUDSON updates the Sapphire Tribute counter with a Shingles Counter, and an Upkeep notifier.

Sclawous:
“…Ok Grotch, two questions. 1) what is with the flying roughdraft of a building, and 2) what is upkeep?”

Grotch:
“Ok, im gonna answer those in the order given: 1) The fortress doesn’t know where to put down the building, since there is no room inside the fortress no more, also farms cannot be placed inside the walls. You simply have to order a place for it to put down the farm! 2) You would not expect us to just waltz around and work for you without payment do you? Upkeep is what you have to pay to keep the army in order and working condition! The bright side is that you can have as many units as you could ever want, the dark side is that they all need to be paid in upkeep!”

Sclawous:
“Well ain’t that a pickle.”

The Unit Stats screen opens and accepts the idea for the Key Golem, but there is not enough Sapphire Tributes to spawn it yet.
