Lack of Items in Clue Easy

I think quite a range of items are potentially missing from the drops of the easy clue scrolls. I'm not sure why some of these may have not found their way into the game, I did notice however that easy clues can include other variants the server currently doesn't house so this may be the reason. Regardless, here is what I found that currently isn't an item on the server.
