Good day KhaineGB, your mod is amazing . I face a problem on my server, someone use vanilla bug to copy blank class paper. They put class book on belt to read, after message pop up they press shift+left click on the class book to put it into bag and then click accept on the pop up massage.They still activate class quest with on class book consumption, scarp the copied one get another blank class paper and study another class. It's easy to change scarp to break the cycle but is there a way to freeze belt when message pop up? you know same method can copy all pop up message quest book such like treasure map.Thanks for your help.
