Only few people know this about CLAG: If no one is in the area of a dropped item when CLAG wipes entities the item won't disapear. For an entitie to disapear the area it is in must be loaded (ie: a player in standing in a 4(Need to check...) Chunk radius of that item)
I believe that this works if the chuck isn't loaded. ^^ So, when you don't see the chunk where the item is, you should be okay, if I recall.
