Friends list DC bug
As reported by user on forum:
There is a bug where if your friend list is "full," and you click the list to view the friends, you get dced (or game crashes... not sure which one).
I talked with my friend and it doesn't seem to be due to # of people on the list, ,but rather # of letters from all the friend list names.
Maybe there is an overflow in something that is causing this crash...
