Right after they revamped treasure chest loot, I did about 100 devious and ingenious maps. I collected about 15 orbs, grapevines and shields. In addition, so many dresses, sashes, kelp leggings, and the female armor, that I was just leaving them in the chests. I also got 5 pardons. It's been a few months since then and I did 150 more maps over the last few days and got one orb, one pardon, two shields, and many fewer of the other items. Was the drop rate changed, or am I having a bad luck streak? Grape vines in particular seem much more rare.
