Create pressing recipe for dark_rune has a 50% chance to crash the game.

"Cannot assign field "locked" because "this.heldItem" is null"

This is due to create requiring an output item but null is given 50% of the time.

Possible fix:

at /kubejs/server_scripts/create.js
change Line 20 from

event.recipes.create.pressing(Item.of('forbidden_arcanus:dark_rune').withChance(0.5), 'forbidden_arcanus:darkstone')

to

event.recipes.create.pressing([Item.of('minecraft:air'), Item.of('forbidden_arcanus:dark_rune').withChance(0.5)], 'forbidden_arcanus:darkstone')

This results in the wanted behavior but with an uglier recipe.

ive changed the recipe to a compacting recipe and it seems to have fixed the error
