I've been getting really weird results with my configuration. Sometimes the drop works, sometimes the drop gets assigned to every single block broken, I'm at a loss right now...

Yeah, I don't know offhand.

Using the debug feature may shed some light on why a rule is not behaving as expected.

Looks like the crash is because a null made it into an items array in one of your scripts.

This can happen with a trailing comma like so:

"items": [
  "minecraft:gravel",
]

I've put a null check in the item parser to eliminate the crash going forward.

Thanks. I tried having debug but nothing would print, was very weird.
