If your extraction includes the SDX packages, some files and strings will not load, causing the manifests and comment mappings to be incomplete. I am unsure what the correct load order is, so I need to do more testing before I can fix this.
Workaround: Until this is fixed, I recommend excluding SDX packages from your extraction, and waiting until those files are patched into the game. If you need the SDX files before they're patched in, extract them by themselves into another directory, and be aware that some comments are going to be missing.
