expandAdventures breaks packing occasionally

[MrVauxs]

Hey, I was greatly enjoying the newly added expandAdventures option when making adventure-heavy premium modules and I have come across an issue.

For some reason one of the adventures has the cli (programmatic, via compilePack) failing on

let [, collection] = doc._key.split("!");
// TypeError: Cannot read properties of undefined (reading 'split')

I confirmed the files do not have a _key in them, but neither do all other expandAdventures exports, and they are building without issue.
I don't know how to fix this exactly since I don't see that expandAdventures exports should have _key, and if they should I don't know what key it would be.

The adventure JSON exists so it should presumably be finding that one first and checking it for its contents. However, by the looks of it the compileClassicLevel doesn't enforce any ordering of the files, so a document belonging to an adventure can be read before the adventure doc.

I can privately provide the extracted adventure data for debugging on Discord or email.

compileClassicLevel checks for a key:

if ( !doc._key ) continue;

So order shouldn't matter. I'm not able to reproduce your issue with the provided adventure. It packs just fine for me.

Turns out this was a bizarre package dependency issue that only appeared on this one module.
