Money is double*1 but for me on an alignment 2, thats why default settings oversee it.

If changing it, and the game makes a money increase, it will see the change and defeat. However if spending first, it will accept the new value. So just pause it, change money, and double click on some unit icon, you get plenty of money.

The nasty thing about the game, some quests still are pesky even with infinite money :-/ or I'm just that a lousy player.
