Title says it all. Happens only in game.
One sided friendships should have also been fixed.
I've had friends get unfriended locally even though I never unfriend people, so the bug where you lose friends locally may occur regardless of doing the above.
Going to add I don't have too many friends on my list (yet) only about 20 or 30.
@狐小百合: Maybe you’re right, but this issue appeared to me when i decided to cleanup my friendslist and removed inactive friends. I saw a correlation here. I have never done it before.
The friend system appears to slowly presenting all these little bugs. they are aware of the initial one sided friend problem but this one might be new and related. I hope they find whats causing all of this soon.
