/**
 * Override / fix for vanilla minecraft using an old server-> client sync system that truncates Integers to Shorts so anything under Short.MAX_VALUE aka 32767 wont work
 * 
 * Look at net.minecraft.inventory.IContainerListener
 * 
 * and you will see
 * 
 * Quote start
 * 
 * Sends two ints to the client-side Container. Used for furnace burning time, smelting progress, brewing progress, and enchanting level. Normally the first int identifies which variable to update,
 * and the second contains the new value. Both are truncated to shorts in non-local SMP.
 * 
 * Quote End
