So, can someone clarify those three options?

; Method of paying unit and improvement gold upkeep

; 0 - The player`s total gold must be non-negative after paying upkeep

; costs associated with each city. If for any city the player`s gold

; is negative, random buildings in the city are sold off. If the gold

; is still negative, then supported units with gold upkeep are

; disbanded.

; 1 - In the first step, the player`s total gold must be non-negative after

; paying upkeep for all buildings within a city. If for any city the

; player`s gold is negative, random buildings in the city are sold off.

; In the second step, gold upkeep for all units is paid in a lump sum.

; If the player does not have enough gold, random units with gold upkeep

; are disbanded.

; 2 - Gold upkeep for all buildings and units is paid in a lump sum after

; all cities have been processed. If the player does not have enough

; gold, alternatively a random buildings from a random cities is sold

; and a random units with gold upkeep is disbanded till the treasury is

; balanced.

If I understand it correctly, the first two do city by city calculation, while the last one does the whole upkeep before calculating income. But none does income first and the upkeep, right?
