14.1.1 QUEST ITEMS

When you quit or die, you will keep most of your personal items, such as
gold, clothes, vials, backpacks, weapons, armour, and so on. However,   
you will drop certain items, such as plants, and all quest-related      
items. Furthermore, quest-items (including dead mobile bodies) will     
reset out of your inventory every so often, so be sure to be relatively 
speedy about completing a quest. The reason this happens is to prevent  
someone from collecting quest items and just holding on to them, thus   
preventing anyone from doing the quests.
