Over the last few days, the diamond confirmation has been temperamental in appearing especially in Crafting on PC and using Flash. I was saving my 260 diamonds, but now have 5, due to them just being taken with no confirmation pop up and I have looked twice and have the correct box checked. The strange pop up did show I spent them if I recall correctly but too late to save them. I would try and repeat the bug but have no diamonds left (only 5). This bug seems to have coincided with the misplaced strange pop up bug that Inno are investigating and I believe is related. I will stand the loss if it helps prevent it happening to other players, but when I'm trying to save up for an expansion, it's a little set back but I'll cope. I hope this can be fixed and will add this report to the ongoing report @Dizzy Lizzie with the FAO.
