Well, it's not really a bug. More like the other way round..
But since the update today, I cannot change my pm bubble images. I liked to do that, because I really hate the standard image for them. So, heh, might change that again maybe. You probably wont, but it's worth a try.
Edit: In case you still dont know what I'm talking about, you could change the pm bubble images before the update by modifying state.png and all the five pmbubble_*.png. That doesnt work anymore
