Invisible chats in online play

Since the person who is chatting cannot determine if their chat is invisible or not, the cause is a little difficult to find, but I believe that it has something to to with a malfunctioning whitelist?

I was seeing this sporadically a couple of hours ago, but shutting down the server fixed the issue for me. It’s probably an issue with crisp again. If it happens tomorrow as well, it might be an issue.
