@Almightypebble Huh, that is really weird. Are there any other plugins that you are using that are message/choice related? I have included YEP Message Core in the testing, and everything is working fine with that. There must be another plugin that is causing an issue. Also, in 'ChoiceList' the 'List' must be capitalized. Not sure if it is in your project or not. Also, you do not have to include 'false' at the end of the command. You only need to include 'true', otherwise it assumes 'false'.
