Issue description:

Crafting manager does not display chained crafters together.

What happens:

In one of the previous versions, the crafting manager will automatic group slots of crafters chained to the same machine together, however, this behavior no longer exists in the latest version; instead, it naively group together crafter slots only by the name of the crafters.

What you expected to happen:

The crafting manager should automatic group slots of crafters chained to the same machine together

Steps to reproduce:

1. Place down a machine, and add a crafting manager to a RS network.
2. Chain three crafters to the machine and connect them to the network, open the crafting manager GUI
3. Observe that the crafting manager naively group one row of crafter slots under the name of the machine, and two rows under the name "Crafter".

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

• Minecraft: 1.12.2
• Forge: 14.23.4.2760
• Refined Storage: 1.6.5

Does this issue occur on a server?
I am playing alone and locally on my laptop.

My current workaround is to rename the crafters to the same name using an anvil.

Weird. I can't reproduce this one.

I'm playing on a 1.6.6 dev version. Can you reproduce it there?

It seems to work fine for some things not for others.

It also didn't update when I replaced the machine with something else.

I have encountered this. It works as expected for most (or all) Thermal Expansion machines, but fails for the EnderIO machines. eg: all three Enhanced Alloy Smelter / Alloy smelter machines do not pass the name through as I'd expect.

Ah, this was caused by a derp on my end. Fixed :)
