[1.7.10] Problem with custom furnace

The__Cow · July 30, 2018

Hello, I recently decided to create a sort of furnace for my mod named Ore Crusher. Every thing works very well except when I leave the save I am on, the items from the bottom and the output goes back into where the blocks smelt and I lose every thing that was into this slot. I hope it's clear.. But here is my classes:
