Friend List Issue

BUG REPORT
Date & Time: Since the Stormblood Early Access
Frequency: Constant
World name: Brynhildr
Character name: Thancred' Tsukino
Steps:
1. When Stormblood launched, several people went missing form my friend list. It had been at a full 200 prior to launch, but when I logged in for early access, there were only about 184 friends. There were also a handful of people missing from my full(128 members) LS.
2. I have been able to add new people, and my LS is now full, but my friend list is having an issue. When I hit 188 friends, it said it was full. It will not let me add anyone else. I just get the "your friend list is full" error message. It won't let other people send requests either. They also get the full message.
Since I know that people do not leave your list when they transfer, delete, or unfriend you, and I did not remove anyone myself, I am wondering what could have happened.
