So, the resolution is quick and easy:
1. From the homepage, click the "Most Recent" link so you are seeing the real-time friend feed.
2. Scroll down to the very bottom of the feed and you'll find a link labeled 'Edit Options'. Click this link.
3. In the resulting dialog box, you'll see that they are setting the number of friends you can see to the default value of 250. Change this to a higher number, up to 5000, which is currently the maximum number of friends you can have. Click the 'Save' button.
That's it. Once you complete these three simple steps, you will be back to seeing all of your friends' farm updates, mafia scores, news on their pets, etc. On second thought, maybe you want to set that number to 0. ;-D
Pass it on...
