Upgrade

An upgrade of the player's choice increases either the building's passive production or its capacity for workers.

Passive production does not require player participation and will never stop.

Active production requires workers and resources for production

Passive production, although convenient for the player and undemanding to management, has a capacity of only 50% of active one

In terms of price, passive production is cheaper because it requires WOOD, but it also blocks the ability to make upgrades in any direction for a while time=4h*building_lvl_coefficient

In this case, the building's Treasury will be increased immediately after the upgrade, and the effect in the form of an increase in production speed will be activated only after the timer expires

Active production requires ORE, has no upgrade cooldown, and the capacity of workers' growth is instant

However, both upgrade branches have common effects:

• Treasury will be upgraded

• The Max prosperity of a settlement will be increased

• The ratio of resources in the treasury to prosperity will be reduced. In some cases, this will also lead to a decrease in the current prosperity of settlement (The exact amount of temporarily lost prosperity is indicated in the upgrade cost)

• The upgrade cost also depends only on the level of the building and does not depend on the choice of the upgrade types made earlier
