Hey my brother is having a similar problem but not exact, he can't see any sort of chat besides /say and only then can he see the chat bubbles. So when he talks in party to me I can see it but he can't when I say something back in party it doesn't display for him this happens with all forms of chat. Since this has happened he has stopped playing due to have virtually no way of communicating with people. Also I received a chat ban for clearing my feed of multiple guild recruit and gold seller spams, but I said nothing offensive and said nothing more or less than the actual spammers, rarely do I ever talk as it is. Any help is appreciated, if no help can be given then please just reply letting me know there is nothing you can do.
