It has been well over a week since I hit my first chest in The Shroud, at least 3 hours overtime. The way I understand it from the wiki is, the timer starts the second I hit my first chest, and regardless of whether or not I loot it just 9 times or 999 times in the week period it should reset after the week is reached..
Is it a bug or have I misunderstood the explanation of Ransack? I am a new player and I didnt even know I was ransacked I just though my loot luck was poor.
