Blackout map shows a grey void. Solution: This is the hallmark of a low-quality dump where the terrain data is missing. You must delete and acquire a proper 80GB+ high quality version. The full game with all maps installed is approximately 85GB.
To ensure you aren't wasting bandwidth on a broken dump, check the release notes for these specific BO4 indicators:
: IX, Voyage of Despair, and Blood of the Dead.
Ensure the PKG size matches the official release (typically over 50GB-100GB depending on updates).
