How to find Battlefield IDs?

[Aeshur]

So I was interested in implementing battlefields in the future for WoTG+ onward content. Most, if not all of these have no IDs available in documentation/battlefield_ids.txt. For reference, I downloaded Purple is the New Black captures from the capture discord to try and see where the ID 2721 pops up and could not find it. Is this just an arbitrary number or am I missing something?

Good question, and I'm not certain how they're derived either. My guess would be that value is packed data in some regard, but typically if you increment by one, it'll match the 32000 event in most cases.
