quest bug
 

I started playing the game and encountered a frustrating bug. I am supposed to bring carts to Riga and then escort them back. I'm attacked by horsearchers and defeat them but after that the quest seems stuck. I've redone the battle a few times but to little avail.
No questionmarks, no events, nothing...
This isn't the first time this has happened but this time there seems to be no way to solve the problem oddly enough. Any suggestions? :(

But you don't see the ! anywhere on the map; in theory you must proceed to same location of before the battle (Koenigsberg if I remember well ).

I replayed the battle a fifth time and this time the questionmark appeared above Konigsberg... the game is great so far but the Quests seem somewhat buggy at times.
