Quark's ShapedExclusionRecipe implements that, but it's shaped as though it was a 3x3 recipe, despite being 2x2.

That's peculiar, doesn't vanilla have a concept for shaped recipes? Oh well, I'll fix this

It does, but only for ShapedRecipe and this can't extend that for technical reasons

Well it isn't showing the shapeless symbol, so I don't think it thinks the recipe is shapeless. It's just being improperly applied to the 3x3 grid instead of 2x2.

boolean shapeless = recipe.fits(1, recipe.getIngredients().size()) && recipe.fits(recipe.getIngredients().size(), 1);
Not sure then, the only other possibility is your class extends shapeless recipe for some reason, which does not look like the case

Oh, actually, this appears to be a Quark bug. Quark is returning true from Recipe.fits given large bounding boxes.

It's still likely reasonable to fix this on the EMI side so I will but yeah

huh. but we do return parent.canCraftInDimensions(width, height); (which i'm assuming is the mojmap for fits)

It only seems to consider the parent recipe's restrictions

well yeah, but the parent recipe is a 2x2 recipe here

Ah, guess I gotta narrow in on the proper size, mods like ct must buffer with empty stacks for alignment. Okay this is my responsibility then.

This is fixed in EMI 1.0.7
