Well, I know this has probably been discussed before, but I search and didn't really find anything. All I found was a few threads with about 15 pages that didn't seem to mention it once.
To the point, as you've probably noticed most(if not all) server's custom items are bugged with the "?" icon. I heard the only way to fix this was to create an item cache with your custom items in it. Well, I'd like to know if there's any sites that help you do this, or if there's any tutorials.
As I've said, I've already searched but I've not found anything yet.
Basically what I'm asking is: Is there a known fix for the "?" custom item bug, and if there is can you point me in the right direction of how to fix it.
