Fails to process PAK structure with versioned _P packs #4
Description
Posting this as a full-fledged issue incase you might want to look into it later.
Tested on Talos 2 demo, 5.2.0 it has IOStore/PAK structure:
Talos2-Windows.pak
Talos2-Windows_0_P.pak
global.ucas
global.utoc
[...]

I think they might be using the little-known "overwrite-delete" file entry that "deletes" assets from original PAK via _P(atch) outright, rather than overwriting?
