Acknowledges that the currently-offered auto-accept quest has been accepted by the player.
- Quests flagged for auto-accept are forced into the player's quest log immediately, rendering accepting the quest a mere formality.
- Calling this function allows the server to keep track of whether it should keep trying to get you to accept the quest via autoquest popups.
- You'll acknowledge the last quest for which the QUEST_DETAIL event fired.
- Patch 5.0.4 (2012-08-28): Added.
