This always used to work in the past, but today, I can’t use the in-game chat when on single player modes. This is a big deal, because it effectively renders cheat codes useless, as you can’t input them when you want to have some fun.
Pressing enter just closes the chat window and no messages are sent. I tried with and without mods, and by restarting my PC and the game. Messages never send, cheat codes or not.
