It's been a month since I posted this and it still hasn't been resolved! So when playing on a server such as The Hive, where chatting is very common... no chat has been showing lately. I have had friends text me privately through Xbox asking why I wasn't replying to messages. They're not showing up! Also, when playing in a friend's world or in my own world with friends, I can usually see the chat of one or two friends, but not the rest of them. I have had this problem for about a month and a half with private worlds, and about one week with servers. I have tried turning on and off the Hide HUD. I'm not sure what else it could be. 

Update: I have a friend who has been having the same problem, also on a PC.

Any help is much appreciated!!
