This bug consists of showing that I'm friends with someone when I'm not. The name turns green, but it doesn't appear in my friends list. However, the name remains green and I can't attack that person in PvP, but I can be attacked, and the person who is actually on the friends list alternates between green and white at certain times.
This needs to be fixed.
Yes, we know the root of the problem. As I already mentioned, it will be fixed.
