I just have got situation that shouldn be possible. I was escorting my Wagon when enemy player tried to rob it. I wanted to defend it so i started the fight. The countdown of fight started as usualy and after 30 sec i got information that enemy fleed. (so nothing special here). But i was shocked that in that time when i was in fight another player just rob my Wagon. It seems it was not protected in that time when i was in fight.
So please check that.
