Someone asked me to include those quests (key,chest,roll) into zz_Worldboss. So I tried to find an event that would indicate when one of those hidden quests is marked.
I tried "QUEST_AUTOCOMPLETE" and "QUEST_LOG_UPDATE" both dont fire. I hate the idea to have it running in an onupdate.
I tested with the chest which is easy enough to find on my empty realm. The key-quest was marked right the moment I looted it from the chest and the chest itself took a few seconds before it was marked. But cant find the right event for this
