NPE on startup when creating input descriptions

[oniatus]

Tested from the latest engine develop branch and fetched the module today:
Used core gameplay, disabled all modules and activated WorkstationCrafting.
Startup produces this exception:

The recipe that is processed in InventoryInputProcessPartCommonSystem.getInputDescriptions is WorkstationCrafting:RecipeStick.

Just to verify: this still happens, with the full NeoTTA template running.

I wanted to take a crack at this, but can't reproduce the error (either with WorkstationCrafting alone, or with all of NeoTTA). Is it possible that this has gotten fixed accidentally?

[Cervator]

Hey @aaron-harris - sorry for missing that message for months :-) Yeah I just tried again, cannot replicate. Accidental fix ftw! Although I see another fix I had marked as maybe related, so that might be it. Closing!
