[1.4.0 beta] Broken handler for Mixer (problem with overriding of method?)

[OneEyeMaker]

Hello.
With GTTweaker 1.4.0 I can't add recipes for Mixer with fluids. For example, any of these recipes:

Mixer.addRecipe(<ThermalFoundation:material:42> * 16, null, [<ore:dustCopper>.firstItem * 11, <ore:dustSterlingSilver>.firstItem * 5], <liquid:redstone> * 4000, 1600, 8);
Mixer.addRecipe(<ThermalFoundation:material:43> * 4, null, [<ore:dustTin>.firstItem * 3, <ore:dustSilver>.firstItem], <liquid:glowstone> * 1000, 400, 8);
Mixer.addRecipe(<ThermalFoundation:material:44> * 4, null, [<ore:dustTin>.firstItem * 2, <ore:dustSilver>.firstItem, <ore:dustPlatinum>.firstItem], <liquid:ender> * 1000, 800, 8);

cause java.lang.Integer cannot be cast to net.minecraft.item.ItemStack.

I guess, MineTweaker tries to run this method instead of that.
Please, fix this problem.

And I sure, that these recipes are correct, because its worked properly on version 1.2.2.

// Also, fix mistake/typo in logger output - Mixer != Lathe 😄

P. S. Sorry for my English. I'm from Russia.
