Burden of TIme --- does it affect computer players?

[Daynarr]

BoT does cause your population to die but at slow rate so it shouldn't affect your income greatly over time (at least not at the rate you are describing it). What does affect your income is unrest it produces. You should use patrollers or reduce taxes to fight unrest in all your provinces. AI usually reduces taxes so when BoT is cast it shows significant drop in income for all non-death players, but it gets steady afterwards.
