Stalker 2: No patch found, falling back to chunk based updates

[jwefers]

For every patch, the entire game gets downloaded again, as all chunks changed. Makes 150GB every time.

Log for updating from 1.1 to 1.1.1 (which should be 1MB download size):

So i would like to help debug and fix this, but i need to know how to abort a started download. Heroic started it, when i run gogdl with debugger now, it just continues the chunk based download, and the v2.py -> Patch.get() method is not called anymore. Advice here would be appreciated.
