I was feeling sth is wrong with bonuses for a long time...

Now I have +15% healing battle priests bonus which counts only to 1 stack of them.

1st stack is healiing like 100 pretorians, 2nd one (exactly the same) like 80 of them...

Btw... I met it first time about a month or two ago.
The situation is as follow:
I fight a battle and after winning it my char appears a screen or two from the place I was doing the fight.
I have lost 2 times resources not able to find them (highland clans) but most of the time I can gather them when going back to the place I was fighting monsters.

Is it me/my pc or it is some added feature so I would not be borred with just grinding, the same as miracles happening in the fight from time to time?
