Was working on the quest series last night (Sat 7th) on my main character Nerisa (59th level Shammy). During handing in the quested items for Brigands Heads & Food supplies the quest giver suddenly cancelled the hand in with messages like:
Trade has been cancelled
The item(s) have been returned to you
Terlas_0000 has cancelled the trade
As the quest givers for each those had only one item to return (and it did return the item). I restarted the trade and handed everything in. In the end I got my 4 unusual crystals and went to turn those in to Mesklin (in EPL). During the turn, I had given 2 of the 4 crystals and suddenly the trade cancelled. Going thru my bags I had only received 1 of the 2 crystals back. So I hand in the remaining 3 crystals hoping it would credit me for 4. Nope, Mesklin returned the 3 crystals. So stuck with 3 of 4 crystals and cannot complete quest.
