Spamming the chat with the period "." character crashes the game, if the narrator is active.
This issue occurred in a single player world.

Whenever I start to spam the chat, the narrator will read the message, and then take a brief pause before reading the next message. However, it cannot keep up with the spam and will soon be many lines behind. Suddenly, the game will freeze. Normally, I'd just Ctrl + Alt + Delete and end the game in task manager, but before this opens, my entire pc will crash saying "Oops, something went wrong" and reboot.
