First of all, whever i gain hero points, it always displays the message twice (though, it doesnt count it twice im pretty sure)
However, when i complete a feat ill see the amount stated in the codex (990,000 since im lv 99) (twice as usual), and then ill see another number (seems random; normally like 624,379 or something. THIS AMOUNT IS ADDED to my hero points (and of course displayed twice).
Now, i personally have no real problem with the bug except it feels like cheating; therefore, im letting the devs know of this; sorry no screen shots.
my hireling is level 99 too, so that explains why i see everything twice, but does not explain the extra hero points i get in addition to normal ones after completing a feat.
