I was in game yesterday and sent this guy a friend request, I knew he’d sent me one before so I sent him one and he accepted, I just checked my friend requests and his friend request still appears even though we’re friends.
I’m not sure how to reproduce but i’d assume you send a friend request to someone who’s sent you a friend request, if they accept it then it should still appear in your pending friend requests.
It happens on the main website, not sure about gametests.
I’m not sure when the bug started happening, but I have only noticed it today.
