Follower notification only works for first follower of the stream

i didnt try the unfollow and follow buissness as i know that doesnt work, people in the stream said they followed but i didnt get any notification, i did however leave the &testsound thing in the URL by accident, i have since removed that but i didnt wanna restart my stream just too see if that fixed it, i would just like some conformation if that was what was wrong with it and if not i would appreciate a fix if there is one
