When running any commands that use discord.Member.nick if there is no guild-specific nickname, it is None and displays "None" to the user.
It is better to use discord.Member.display_name, as it will always return a name that can be used without the fear of it being None
Commands affected by this:
- /cool
- /dev
- /dragon
- /furry
- /hewwo (?) When there is no guild nickname it is replaced to the username
- /quote
