Sometimes the chat can't let me press "a" more than once. Whether I use "enter", "t" or "/", it won't let me type "a" 2 times. When it does press "a", it erase the messages I was writing at the same time. And force me to use "ctrl" + "v" / "c" to copy/paste a bank of the letter "a".

The only way to fix it as of now is to restart the game.

Please fix this.
