as title states, i cannot use any pills in proving grounds and I killed all of the moon turtles (about 11) and got nothing from them. Is this working as intended?
It might be a good idea to move the Health Pills, Health Tablets, Chi Pills, Chi Tablets, Rejuvenation Pills, and Rejuvenation Tablets from your inventory to the Action Bar. If you tap the keys on your keyboard that correspond to the various slots on the action bar then you will be able to restore your Health and Chi.
