Questions regarding quest mechanics
 

1) Currently, do quest npc's retain memory of items turned in upon death or despawn? I saw a thread where this was bug reported, but didn't seem that devs were convinced.

2) If a quest turn in has multiple items, but I turn in 1 at a time, is that considered "multiquesting?" Would this result in failed quest turn in for quests not flagged MQable (plane of sky comes to mind.)

3) Are there any relatively easy quests that are flagged as no mq that i could test this on?
