I am having a blast hunting for lock chests to pick. But it is increasingly difficult to find chests to unlock. I unlock all the chests that I can at my current skill level then I have to go back to a door and raise 5 or more skill points to unlock more complex locks and repeat the cycle.
In other words my problem is that I can no longer find chests to unlock at my current skill level. I must practice on locked doors that reset every 10 minutes. Then when I gain 5 or 10 skill points I can go unlock more complex locks.
