Tried a series of tests, and while not finding any missing items, I did find the following problems:
- "Noob" equipment such as "Beater"s are allowed. While this isn't really a bug, I'm not sure it's intended?
- The hypen character "-" isn't allowed, so certain items which should be legal (I'm thinking of Lo-om equipment) isn't allowed, whereas other leathercraft sets are. The colon character is also blocked, which means that making a quest for Schemes or BPs is impossible (although this is perhaps by design?)
- Perhaps by design, containers are not valid quest targets.
- When creating a quest, if the player splits an item from his inventory and puts the split item straight into the quest reward area (without creating separate stacks in their inventory), the quest creation fails. (Interestingly these messages didn't fit properly into the chat window - I have System messages printing into the default chat window -

I can't think of any more tests right now. If I find anything else I'll let you know!
