So I was playing with my friend and after a short while, we couldn't see what we were saying to each other. It happened to me first when I couldn't see my friend's chat, he just kept walking around. Then it happened to him, when I could see what he was saying but he couldn't see what I was saying. Is there any explanation to this? There was no lag and we never disconnected. (the session ran for about 5-6 minutes before we gave up)
