I had this behavior before, but thought it might be an accident, as I had the medals quest before but it was not further counting toward the 285 target after I reached 250 total medals.
So I checked the quest progress prior to attacking and afterwards. No progress was made, even though I won some fights. As you can see in the following screenshot I have 249/285 medals
And my last attack was versus B 020
After my troops were rebuild I attacked again:
As you can see I won two fights and the medal count didn't change at all:
Also you see that in the first screenshot the Exotic Goods quest did have 0/155 goods and after a restart of the app the number updated.
