not sure why you would say that you have to be not playing the game to follow it. I open 2 windows, 1 with the game and 1 with discord. I can read and chat while my girls are fighting insects during fast forward. I mean all I have to do is press fast forward whenever the sound stops.

some discord invites expire after a period of time and you need to change the settings for it to be permanent and unlimited uses.
