When going in the suldanessomething (the elven city in act 7 where Irenicus is supposed to be) I thought that I don't want to complete the game yet and went back to Atkathla to complete some quests. Well now it is impossible to get back to the city. In the travelling screen the game says that the destination is not available and when I travel to the map where you would normally reach the city (some kind of forest) there is no way to reach the doorway which leads to the city because I always got in the wrong side of the map.
Any suggestions or do I just have to play through the whole game again?
