This is an official report for an issue Wrecked Avent already knows about and might remember.
As one of my characters, I sent someone else a friend request. Then, I accidentally cancelled it, and hurriedly resent it. Sometime before, during, or after that process, they accepted the original friend request they got, and now we're out of sync — we don't see "befriend" or "defriend" at the same time, we're like marching through different cycles and out of sync somehow.
