Maybe I'm wrong - but if I remember correctly, previously when someone bought my auction of, say, 2 Purple Flowers, I would see a notification on my Home page saying something like "Dorkface purchased your auction of 2x Purple Flowers, for 150 currants."
This afternoon I'm seeing this format instead: "1padme purchased your auction of 1x , for 80 currants." with no item getting inserted after the quantity.
