Interestingly, that is already on the list of tracked trophies:
http://www.trophyhunteronline.com/trophies.php
and has 0 pickups. The only time i've seen this is a wierd case where
the AC item actually has trailing spaces in its name, or some other
wierd mispelling or special character.
I haven't actively played in years, so i've never seen one. you may
need to use some other plug-in to find exactly what AC thinks the item
is named and let me know?
