[Nagot Gick Fel]

Order of events:

(a) Bloodhunting
(b) Unrest rises
(c) Tax collection
(d) Patrols decrease unrest

So, assume your capital nets you 200 gold/turn at zero unrest, assume unrest rises to 50 because of bloodhunting (thus cutting your income in half), and assume patrols reduce unrest to zero. Next turn your income will still be listed as ~200, but there's 100 less gold than expected in your treasury.
