Requiem Shard

Apparently, when one item sells out from the shop, the arrays shift, and you have to click another item in the shop to get the one you actually want.

In this example, clicking Summer Sweat tries to sell you Black Flour. If you actually want Black Flour, that is where you have to click to get it. Once sold out, the arrays shift another spot.

(I've restocked and cleaned up the vendor to have unlimited supply until the bug itself is addressed)
