Exception in thread "RS crafting preview calculation"

Issue description:

Seriously bad lag spikes and can’t craft a hardened upgrade, or access two of my crafters, one of which contained the pattern for it.

What happens:

I opened up my wireless crafting terminal to make a hardened upgrade for a machine, and also requested a reinforced. I then realised that I wanted another hardened for another machine, and when I clicked on the start button, it just greyed out. This is within ~5-10 seconds After getting really confused and requesting it a couple more times, I closed the wireless crafting terminal and went to check on the crafter and noticed that I was getting extremely bad lag. I went down to my crafters to check on them and right clicking would open some of them, but not two that I tried. I broke a cable and the network controller, still massive lag so I clicked save and quit.

After reloading the world, it looks like the save and quit failed hard as the cable and controller were still in place and I’d never made the requests. As it turns out I was out of nickel, but it never made it that far - my nickel would be in a locked storage drawer if I had any, so it might be related to that.

What you expected to happen:

It to make a hardened upgrade for me!

Steps to reproduce:

1. Unsure, it worked completely fine up until now (I’ve crafted dozens of upgrades) and since, hopefully a one-off. I wanted to report this just in case it is something you can easily stop from happening, in case it corrupts someone’s world next time.

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

Since this is drawer-related, I wonder if this bug I reported to StorageDrawers is relevant at all?

OK I’ve replicated it properly now;

1. Have an RS network with a storage drawer controller attached via an external storage.
2. Have an empty compacting drawer attached locked to, say, nickel.
3. Have another empty drawer locked to NOTHING.
4. Request a non-processing recipe requiring an item from the compacting drawer.

Random AF and probably a corner case (who besides me would actually attach an empty drawer on purpose? I was mapping out my storage room) but there you go.
