I happened to look at my user in discord and found that I have a bunch of game_1_member and game_1_administrator roles added to it after running a bunch of startgame tests. I believe these roles are used to restrict access to game channels, though I haven't looked into it in detail. But it appears that discord does not prevent custom roles with the same name be added to a user, so we should clean this up. I'd suggest:
rename the roles to be Secret Hitler specific...perhaps sh_game1_member or something like that
verify the role doesn't already exist on the guild. If it does, modify the name in some way to be unique
check if the user already has the role in question before adding it
remove roles from users at game end and at Secret Hitler server shutdown
