The invTypes table says 4km3 - which is as expected
Since there is a packaged volume as well, i expected to find “1km3” in invVolumes.
But id=41493 is not there at all.
I don’t think packaged volume have ever been in the SDE?
It is in ESI, though: https://esi.evetech.net/ui#/Universe/get_universe_types_type_id packaged_volume (optional - set for anything that have another volume packed)
Note I have only found it in the following categories (if you want to minimize your requests to ESI): Ship, Module, Celestial
EDIT: it’s not in the yaml files, so, I’m guessing it’s something Steve maintain himself
