Admin Forum:What's happening with transparency on achievement icons?

Following the MW 1.19 update, some achievement icon are still transparent and some of them now have an ugly black background. Why? It seems totally random to me. As the creator of most of the icons seen at tardis:Special:Leaderboard, I know they were all made the same way, so there can't be a technical difference between them. So what gives? 07:20: Wed 15 Aug 2012

That happened to me too. What I did was remove the images. But then, I couldn't add new ones. It let me add pictures in a few days, so I don't think it will last long. 21:39, August 15, 2012 (UTC)
