Consumer facing "mistakes" like this should not be adjusted to negatively affect the consumer. If it dropped at "310" by "mistake" then the development team responsible for doing this should be reprimanded and future drops from the daily heroic mission for this should be fixed, but the consumer should not have to suffer that already obtained this item. Also it was not made clear that all black spindles (including on the exotic weapon wall for purchase with coins and shards) were also "mistakes". They dropped all black spindles by 20 points, not just the drop from the daily. Furthermore, that daily was stupid hard and deserves to have a 310 drop for that. #feedback
