Not really an issue, but more just for analysis sake

Here is a comprehensive JSON with all the droppers, quantities, and contents. If analyzed, it could show what droppers are missing contents
Droppers.json

Thanks. This definetly will be useful if I get back to upgrading this.

I wrote a script comparing coords I have with your json, and I can share these as something you didn't have in your list (although there are 2 non-droppers here - one waste chest and one backlog barrel):
