Cannot interact with essential character
Before going any further i must apologize because i don't know the name of the quest in english. In the main quest where you have to find the gathering point of the mercenaries who are trying to create an army in Sassau at one point the executioner talks about an injured guy in the big church to the north of Sassau. Then I have the objective "Talk to the injured guy", i have the market, I see the guy on the bed however i cannot interact with him.
PS: for more precision, this the quest where you have to ask the mayor of Sassau, the two bartenders of Sassau if they saw any mercenaries in Sassau. Also it is the quest where you have to talk to Simon (the guy responsible of the mill at the north-east of Sassau).
