It shouldn't, but even with the well-known glitch that was causing people to buy Valor Coronet when they clicked on Thavnairian Mist (the two items are in different tabs, so it's very unlikely to be user error), SE tells these people that they have to either eat the loss or use their one-time restore to fix this.

After the number of posts I saw about this, I bought my Mists one at a time as soon as I had the 300 myth, so if I clicked too fast and it tried to buy something else, it would fail.
