Issue description:

Your Crafting Terminal doesn't want to show the output item for recipes that do not extend the provided recipe classes but instead use their own implementation of the IRecipe / IRecipeShaped class.

This issue ONLY happens on a server and is only a visual glitch, @kindlich has tested that and may have more info.

What happens:

Recipes added via CraftTweaker now use their own IRecipe implementation, so any recipe added via CraftTweaker will cause RS to glitch out and not display an item in the output slot.

What you expected to happen:

An item to be displayed in the output slot.

Steps to reproduce:

1. Add recipe with CraftTweaker
2. Start server
3. try and craft said recipe in a RS crafting grid

Version (make sure you are on the latest version before reporting):

• Minecraft:1.12.2
• Forge: 14.23.2.2624
• Refined Storage: 1.5.31

Does this issue occur on a server? [yes/no]
yes

Did you look in the code to confirm this? Your comment comes over as you're sure about this theory.

I checked the code, didn't find anything out of place there.
Here's what's happening with a shaped recipe:

If I make the recipe class extend the ShapedRecipes class, it works as expected.

Can I see your recipe implementation?

We've narrowed it down to it being most likely an issue on our side, since we were calculating recipe names from the ingredient. Turns out MC doesn't override toString or hashcode

Can most likely be closed
Issue were differing recipe names.
