I apologize for any problems with the "auto-collection" submissions. It pulls in items that exist in the game data files, whether they can actually be obtained in game or not. It does filter some things out, such as spell scrolls and items tagged for above level 75.
In the future, the auto-collected item data is going to be forwarded to pikko or haggan for entry, instead of having a script guess at whether it should be adding an item or not. (This one was entered by hand (mine) after verifying it was indeed available on the AH)
