It's been a while since I've actually had time to work on my database, but it seems with the latest patch, 2.0.3, the wiki is becoming quite outdated.. either that or for some strange reason my parser is bugged.
CreatureCache, QuestCache, and ItemCache all seem to be missing fields. I'm going to be restoring some of my previous scripts today to debug the files (as my parser simply goes from wdb->sql) so I'll know more then.
I take it back, QuestCache seems to be up to date.. although I'm not 100% as the db is relational so I have to update the Spell's listing in it first (extracting those now)
