A chunk of the conversation disappeared.

I was working on a campaign, got to a good stopping point, and left the chat. I opened a different conversation and then later came back to it. When I came back, more than half of the chat was missing from the feed. I asked in the chat if the information was still there, and it had everything and repeated it back to me, showing me the drafts that it had created. I left the chat again, came back, and all of the chat was back. Where it was originally, including the new chat that told me everything was still there, underneath everything, for some reason it just disappeared from the message log briefly and then came back after leaving and returning.
