[GAMEPLAY] Odd chat message during game

During the beginning of a recent game(around 0:50 on the game timer), an odd message appeared in the chat box. The time stamp was incorrect for the game clock, and was not displayed in a way that a chat message is typically shown. Attached is a screenshot of the message. There was a second message as well a few seconds later that I did not capture, but it was similar in nature. As shown by the screenshot, other players saw the message as well. I posted this in a support ticket and was told to post what happened here. If the original version of the image is needed, I can provide it as well, but thought it would be best not to post other usernames unless instructed to.
