Random crashes with NullPointerException.

See crash report:
crash-2023-03-29_15.38.18-server.txt

when this crash happens? request crafting jobs or just randomly crushes?

It happened when canceling a crafting

well i can't reproduce the crash. could you give me screenshot of which crafting job you are canceling?

Looks like Plethora can interact with AE from another thread. Not sure how to go about that

It should always use the main thread unless worldThread = false is specified in the @PlethoraMethod decorator.
All interactions should be performed from the main thread unless I missed something (I also debugged the craft method and it is in fact called from the server thread)

Posted on AE as well since it's probably unrelated to AE2FC: https://github.com/PrototypeTrousers/Applied-Energistics-2/issues/255
