Let me try to explain. What you see in our database is always the base item. From there, some of these items are dropped with a random property added on. In effect, these are like enchantments that are built into that copy of the item, and they're selected randomly from a really big table. We can show the correct version of the item in profiles because the id number for that version is uploaded.
We don't show the randomized versions of the items for things like item searches and mob loot because there can be so many of them. Also, as far as I can tell, all of the randomized versions of each base item can be dropped at random from the same level range of mobs, so seperate statistics for each version arent much use there either. To give some idea of what I mean.. there are currently 9974 items in our database. 1569 of those are ones marked as being the base for randomized items. For each of those, there would be 10+ versions.. and even more if you counted every iteration of the same stat combinations with different values (ie. considering a +2 strength version to be different from a +1 strength version).
One thing I can do for now is to add a tag to the display for items that can be randomized. If anyone has any better ideas on how to handle this, I'd be open to suggestions.
