I petitioned this in game yesterday it happened on my magician, Malagar on the sister island. I sold all my loot just fine. Then scrolled his inventory for words i might need for research. I found words of dimension, just 1 of them for 5 gold and change, i clicked buy and it charged me 65 platinum and change and didn't even give me the words! I took a screen shot of this and will try to include it if i can figure out how.
