[1.189.041][ModAPI] MessageEntered does not detect messages sent by terminal global chat.
1. Have a world with this mod: https://steamcommunity.com/sharedfiles/filedetails/?id=463098656
2. Type something in chat to confirm the mod is active (it will say global chat is disabled).
3. Open terminal -> comms and send a global chat message with that window.
Now your message was sent and the mod could not stop it because the MessageEntered event did not trigger.
