Strange situation on Kobolt Assault on Elite. My character "Bredy" summoned Hireling, which did not appear in the party. He has been in the quest area, but his name has dark-blue title like character which is not member of the party. He still carried out the commands. Kobolts started fighting and after while they stopped moving. It is possible, that this can be reason of crash.
Party consists of two rangers: Bredy 5lvl and Bargis 2lvl, two hirelings and one wolf. See log files, if you find reason for this stange behaviour. Bargis has been dead while crash and he probably tried to reach the shrine.
