I was playing a mission called "Big Darwa Fort" and the objective is to capture a person named "Dah". So at that time I was running low ammo for most of my weapon, therefore I went to ride on a mammoth and killed all the enemies, I did notice Dah appearing but I wasn't aware where he is so I killed him directly. I wonder will he respond and let me continue the mission or I will never be able to continue my game (because as far as I notice this is one of the essential objective in order to complete the main story line. If the person couldn't respond then that will be sort of a bug and I will want it to be fixed if so.
