Astrum's "other" income was indeed zero. My tax report goes like this:
Libidizedd: 634 gold
Duchy taxes from the other two regions in the duchy: 17 gold
Realm taxes from the other duchies: 104
Crown's total income: 755
The game reports: The crown has received 755 gold tax income thanks to a realm share of 5 %.
All good so far. The table all calculates out and adds up. But then we get this:
In addition, the realm made 0 gold from other sources (fines, etc.), bringing the crown's total income to 2379 gold.
So, we had 0 income from other sources, which is probably right. But 755 + 0 does not equal 2,379! Where did that extra 1,624 gold come from? And I really did get it, too!
