### Additional context

_No response_

Load the attached Bayou Meto-trimmed.tar.gz save on the reported Windows game version and follow the reproduction steps: move left near the building. Trace the zombie spawning behavior around that location, then verify that zombies no longer spawn directly on the player and that normal spawning still works.
