What does this error msg mean?
 

I keep getting Error: Item with pick id XXX does not exist on <character> when trying to add or edit stuff on my character. The id # changes pretty much every time. This happens a lot when trying to upgrade runes on weapons or armor. The upgrade appears to take, that is, later when I go to "play" the upgrade is shown, but the cost was never deducted from my cash. Also the upgrade price for a particular rune seems to always include the cost of the rune being replaced, which is not, as far as I can see, correct.
