I was using the beta wardrobe (http://subeta.net/wardrobe_beta.php) and viewed the chest category with "All Items on Subeta" enabled, when an event popped up saying that I'd earned the Off my Chest achievement. I thought this was odd because I had, only minutes before, already got this event when I viewed my Chest layer. I checked in my achievements and realised that I'd been given the 1,500 items tier. And I don't have more than 600-something items in my Chest layer, so this seems wrong. I've filed a ticket and got the achievement removed (and re-granted for the appropriate tier when I opened my Chest layer again, without using "All Items on Subeta"). I have not tested using the "All Items on Subeta" option again. I'm using Fedora 20 with Firefox 32.0.

Go ahead and file a ticket, please - I made a report for the Programmers. :)

I've already filed a ticket ^^
