Hey, thanks for the report!

The issue here is that Curseforge does not support requests by slug directly, that's why pacmc uses a workaround at the moment, which sadly does not work that great. This workaround can be improved though, and that is planned for the future!

The feedback for empty transactions can be improved as well, since it might confuse users.
