Lost 495 Mythology tokens

[Selluna]

Today I reached 900 myth tokens and I went to buy 3x Thavnarian Mists from the vendor in revenants toll. Brought one. Brought a second one. And it told me I didn't have enough myth for a third. According to it, I only had 120 myth. So I relogged thinking it was a bug. When I came back in, I had 105 myth and I had only 1 bottle of the mists. Please can someone fix this for me.

Figured out what happened. After buying it for the first time, the tabs apparently reset back to what they were when you opened them... WITHOUT actually showing that they reset back. So I clicked on the Mists again the second time but what it actually selected was the WHM helm that was first on the armor list. It was still displaying to me the Items list. So I clicked buy and it charged me 495 tokens for a item I can't use...
