FAQ
Q1. how this plugin works? A: this plugin creates similar keys like your crate plugin but it injects with a uuid and save that uuid in a file, when you click a crate with that key it ckeck the uuid of key and key in file if its same no alert will be given.
Q2. which plugins it supports? A: it should support any crate plugin which works when you click a crate with key. means if your crate plugin checks players inventor then this plugin is not for you. this plugin is tested with crazycrates.
