How did it happen?

When trying to remove/change recipes with KubeJS, IE multiblock recipes seems to be weirdly unaffected, and crash the game when trying to run reload after the game has loaded. The issue seems to be on IE's end, so I'm reporting here. The issue persists on
build 155, but no crash reports seem to be generated.

Crash Log

Please upload the KJS script you used here, the crash looks like you tried to set a metal press recipe output to air (which is not supported)

Here it is: https://gist.github.com/nexonerr/e8ef8ad4a4ca2d90b892e15d2551762b
I'm not sure if the problem is with the script itself, but the crash only occurs when IE is present, and the functionality DOES work, which is what led me to believe it was with IE, but I'm not 100% sure either

This is a bug in your script. When a recipe uses e.g. forge:ingots/gold as the output, none of the items in the tag have a priority from your array (the tag only contains the vanilla gold ingot). Your script tries to replace the output with undefined in that case, which KJS turns into air. One fix would be to initialize maxPriority to -1 instead of 0, that way the first element of the array will be used if none of them have a "proper" priority.
