Full log: https://gist.github.com/theZorro266/fc58cc5711ce6a85d5d7
I have a fluid container supplier pipe attached to the bottom of an Extra Utilities drum set to supply gregtech oxygen cells to the drum. When the cell gets to the drum is when this exception happens. I'll also see instances of #889 around this issue. After the crash the pipe must be deleted with an editor before the world can be loaded again.

What I'm expecting to happen is that the logistic system will send oxygen cells to the drum until it supplies the amount specified while returning the empty cells back to be sorted.

The only thing I can find is:

java.lang.NullPointerException
    at xk.xact.api.CraftingHandler.findAndGetRecipeIngredients(CraftingHandler.java:424) ~[CraftingHandler.class:?]

Did you upload the correct log?

It was the right log when I posted the issue... it's since been overwritten by another ticket I posted on a different repository. I'll have to post a new log.

Stupid github won't let me attach it. ("Try again with a PNG, GIF, JPG, DOCX, PPTX, XLSX, TXT, PDF, or ZIP.)

Edit: I added the logfile in a gist to the first post /theZorro266

Cannot reproduce.
