string troubleshooting

import crafttweaker.item.IItemStack;

<ore:twine>.add(<betterwithmods:material:3>);
<ore:twine>.remove(<minecraft:string>);

//Change String recipes to use OreDict
recipes.replaceAllOccurences(<minecraft:string>, <ore:twine>, <*>.only(function(item) {
    return !isNull(item) & !<minecraft:wool>.matches(item);
}));

<ore:string>.add(<minecraft:beef>);

//Adds a recipe for nametags
recipes.addShaped("nametag", <minecraft:name_tag> * 2, [[<minecraft:string>, <minecraft:string>, null],[<minecraft:string>, <ore:paper>, null], [null, null, <ore:dyeBlack>]]);

//Okay, so the replacement script itself works fine.
//I am now testing it with the oredict added to the pyrotech items.
//Weird. That changes it to use the string oredict instead! wat.
//Now testing with BWM added, without the oredict added to the bwm string.
//That worked fine. Now testing it while adding twine to the BWM hemp fibers.
//That also worked. Now testing it by adding a non-string thing to oredict.
//That borks it. One more test: what happens if I put the string oredict under the replaceall line?
//Still bork.
//Now, testing to see if it affect custom recipes.
//It does.
//Now, per request. I have removed minecraft:string from the twine oredict to see how it handles that.
//Everything is still accepts any: string. And it's still ignoring the wool exemption.
