I started a game  had two cities and I was earning what I assume was a bugged amount of close to +700g per turn (should have been -maybe- +400g).  I had roughly 35000 gold in my treasury. This was when I saved and quit the game. When I came back to continue playing and reloaded the game I was now only earning the base amount from each city, about 30g per city.

A fix for this would be much appreciated since I was unable to demolish and rebuild the Treasury Vault.

Okay so apparently it decides when it wants to work because now I'm earning +1100g at 45000g in my treasury. (still a glitched amount)

I'll add that before I saved and went to bed last night I was earning about 60000g a season and when I load now it's 47g, then a few turns in after using some gold it's at about 100000g a season. I have a treasury of 5.4 million gold
