I have Discord Auth. It works fine with Discord Core and Discord Core Roles, but when a player authenticates, they get two messages.  One says That is not a valid code and a message that says Thank you for authenticating your account. Discord Auth is working because they get the oxide role after authenticating. So, is Discord Core seeing the code and its giving the message?

Can you show what messages they are receiving and also can I see your DiscordCore config? Be sure to remove the bot token.

Looks like that isn't coming from DiscordCore. That message is from Discord Rewards. Also if you aren't using DiscordCore as the linking plugin you should set "Enable Linking Discord To Rust" to "false"

Ok, thank you. I don't use Discord Rewards anymore but I left the plugin on the server. I'll remove that and change that setting. Thanks for the quick reply!

Np. Happy to help.
