I have had this issue occur a few times now, but it's sporadic when it happens. Sometimes, I will be part way through a game and the buttons for talking to the ref stop working. I noticed they stopped providing a message but I originally wasn't sure if the messages just weren't showing or if the buttons weren't working. This last time, I rode the yell at refs button after it started and they never called a tech on me, etc.
Has anyone else had this occur?
