TBG

[battleguts]

I am seeing a ton of inconsistencies with the amount of turn based gold you get per soldier. I checked untrained and then attack, defense, and the spies and sentries. At one point my TBG went down by 10 gold per turn after I added 165 defense soldiers the next day.
Does anyone know what the breakdown is?

You should get 1 gold per soldier (whether attack, defense, or untrained) and 0.1 gold per covert operative. Mercs do not generate TBG. You can also increase your TBG by upgrading your economy.

At least, that was how it was calculated last time I checked.
