hi,
i've been lurking my way through the archives for a while and couldn't find an answer to this so i thought it's time to lurk no more...
in campaign mode i usually try to install high acumen governors (4 feather minimum) but quite often many years down the line i find that the same governor has 6 or 7 feathers.
the only reasons i can think of for this is that i try to keep loyalty at 200% by lowering taxes wherever possible, rather than using garrisons. there's always the greed vice, but i'm pretty sure this isn't what's happening as that seems to appear when i keep taxes at very high in the province all the time..
any ideas?
