I've had 2 strange things happen to my friends list today.

First one, my friends list went down and said I only had 5 friends total. I had been logged in for about an hour and it just suddenly changed. Restarted the app and it was fixed. Later in the day I checked my friends list again, and it wasn't even my friends list! And no I was not looking at the guild page. It seemed like my friends list smashed with someone else's. Again, restarting the app fixed it.

Don't know if anyone else is experiencing this, but I wanted to throw it out there.
