Thank you for making this plugin, I'm looking forward to using it. When a member leaves discord this error occurs:

(09:49:22) | Failed to call hook 'Discord_MemberRemoved' on plugin 'DiscordConnect v1.0.6' (NullReferenceException: Object reference not set to an instance of an object)

Also I want to mention that the data\DiscordConnect.json file is storing the code they get as the GameId not their Steam ID:

{
"GameId": "30b250",
"DiscordId": "22608742777454336"
},

Is this correct?

don't think so that's messed up
