RTF is a global modification that replaces all towns in the game.

And also, whose values are you looking at? And how do you calculate the upgrades first and then the downgrades? Or vice versa?

I look at who has the higher growth rate:D
downgrade - creatures that are calculated normally
upgrade - creatures that the calculator suggests upgrading to the next level, but we take the growth rate as if they were not upgraded
we calculate the price of the upgraded creatures like this - we take the price that needs to be paid for the weekly growth of creatures with a castle and adjust it so that it fits within 28000.
