Expected Behavior

end coal ore and end iron ore should be smeltable like shown in the recipe viewer (both when looking up the steam oven, or the ore)

Actual Behavior

putting in 1, 8 or 64 end iron/coal ore will not start the smelting process - the steam oven is formed, not on/over a chunk edge and the steam input hatch is full. iron ingots are smelted without issues into wrought iron.

these ores are smeltable in a vanilla furnace without issues and produce 2 ingots / 4 coal as shown in JEI/EMI.

NOTE: the iron ingot -> wrought iron is added by kubejs:
event.smelting('gtceu:wrought_iron_ingot', 'minecraft:iron_ingot')

Steps to Reproduce

1. build steam oven
2. fill steam hatch
3. put end iron/coal ore into the input bus

Additional Information

I looked at the code and it doesn't seem that it's related to a config option - but these are some config options which may be related:
disableManualCompression: true
harderBrickRecipes: true
nerfWoodCrafting: true
hardWoodRecipes: true
hardIronRecipes: true
hardRedstoneRecipes: true
hardToolArmorRecipes: true
hardMiscRecipes: true
hardGlassRecipes: true
nerfPaperCrafting: true
hardAdvancedIronRecipes: true
harderCharcoalRecipe: true
flintAndSteelRequireSteel: true
removeVanillaBlockRecipes: true
removeVanillaTNTRecipe: true

This issue seems to go a lot deeper than it initially appears. It looks like any generated smelting recipe works in a regular furnace but not in any GT furnaces (steam oven, electric furnace, multi smelter). Needs further testing.
