I'm sorry for a somewhat confusing topic title, and let me explain what is happening. I maintain two blogs using wordpress.com, one is at http://soundandcomplete.com (custom domain) and the other one is at http://piotrandkarolina.wordpress.com. In the past, whenever I accessed a list of static pages or media in wp-admin, I was given a list of those that were created/displayed at a respective blog. Now I get sites and media from both my blogs in both admin panels, which is confusing when I have pages called 'blog' or 'home' on both sites.
If this is a feature, then it's a bad one. If it's a bug, then I hope it gets fixed soon(-ish). Is anyone else affected?
