Furnaces, blast furnaces, and smokers delete all of their contents inside them once reloaded after smelting items

Description:

Furnace deletes all its content and is stuck in "smelting" mode when unloading it and while it's smelting you generate a buried treasyre map

This was while the experiment "Winter Drop" was on

Ways to reproduce:

1) Smelt something in a furnace

2) Unload the furncase while smelting

3) locate a newly generated shipwreck that has the map chest

4) Open the chest with the map

5) Come back to the furnace

Expected Result:

When you load the furnace again, the smelting continues from where it is left off

Observed Result:

Furnace is stuck in "smelting" mode but has no items inside of it

Notes:

I am not sure if it the map that is causing it, it may be the chest generating the loot or maybe the newly generated strucure
