I've solved an issue that was preventing players from calling each other even when their numbers were correct, which was causing the entire calling system to fail.
This should be working correctly in this version. There were also some errors when sending messages, which have also been fixed.
I invite you to join my Discord to hear your suggestions or questions.
I missed translating a part when using /customsim, this is already fixed, you just need to delete the messages.yml file for the new one to be generated.
I've added permissions to use the commands so that players with more authority can better control their usage.
