In IgnoreList.java appears that you wanted to add a default blacklist of troublesome containers, but it's not being applied on new install

They all do get referenced, the list that it's in will prevent its inventory from being sorted, not the players too. It should then be moved to the hiddenList, which will prevent both inventories. Sorry I'm on mobile

See https://github.com/kyrptonaught/Inventory-Sorter/blob/master/src/main/java/net/kyrptonaught/inventorysorter/InventoryHelper.java line 65.

And https://github.com/kyrptonaught/Inventory-Sorter/blob/master/src/main/java/net/kyrptonaught/inventorysorter/mixin/MixinContainerScreen.java line 52

oh sorry, I'm a little confused since the json file doesn't get filled
