Missing Items

2 Days ago I noticed a jewel missing.
Today I had 2 Breach Stones, the 2 stones are gone.

No one has logged into my account other than myself. For a fact those stones disappeared while I was playing which is very odd. They are not misplaced just gone. I did not sell them or use them as I was planning to make a 3rd Stone to convert the 3 into the currency exchange for 2 Div.
