Not enough gold in Demonic war

Hello,

Balthar

Field (1476)

Question:

In my first ally i got gold in demonic war till i made 7.000.000.000.000 damage.

Now i have a little ally just for gold collecting. But there i get only gold till i made 6.000.000.000.000 damage (screenshot

shows 6.683.431.870.562 damage but no gold as result for won fight)

Why less gold? I need it for SS tycoon.
