/**
* Why do we need this you ask?
* <p>
* In 1.8.x, Mojang added Twitch integration, and in standard Mojang fashion completely broke inventory handling.
* <p>
* Specifically, you are able to close an inventory and not actually trigger an InventoryCloseEvent. This kinda breaks
* literally anything relying on that event.
* <p>
* So we just add lots of strict checks to make sure they can't do much without closing the inventory
