I will follow up and add to this thread.
I have some 80+ friends on my list. Only 10 show up in both the My Profile list on the left(the one with the green dots), and in the Game Window/Friends list. The 10 people that show up in that list were not the first I added to my list, nor are they the most recent, nor are they the people I contact the most. So the big issue here is not being able to see whether the other 70+ on my friends list are online without having to physically go to their profile page and see if they are available or not. This defintely needs to be addressed.
The other issue, as stated above by IBGPN, is this: When one clicks on the My Profile link on the home page, the number of friends listed in the top section(where Career Earnings and Friends are reported) briefly shows as the correct number, then quickly amends itself to 10. I will also add that sometimes, in my Awards, I have an award for my friends, other times that award disappears entirely. It's a minor issue of course, but a bug nevertheless.
