The GC Supply and Provision list seems to have a bug where, AFTER you obtain the amount of items needed, if you did not previously have them, the item you need to turn in suddenly changes to something else. (Very aggravating if you've taken the time to procure enough HQ materials or craft an HQ item.)

Also, occasionally when this happens, it can trigger classes who's daily items you've turned in to reset, giving you another daily to turn in.

Lastly, despite unlocking all eight crafts, one of them is not showing up in the list. Even though I haven't turned in anything for it yet. (In my case today, it's Goldsmithing)
