During the "flashback" sequences of the Demon Within campaign mission (held on the map cp_mi_cairo_infection2), the Firefly Swarm cyber core doesn't function properly - the fireflies will circle around in-place rather than seeking out enemies as they do in the Windows version of the game.

This is very likely intentional, although the reason why is unclear - specifically only in the Mac port during HKAI_InitMapData when reading out the Havok navvolumes, the smallNavVolumeSettings and smallNavVolumeMediator sections of the nav volume is skipped specifically only on the map cp_mi_cairo_infection2.

A basic attempt at running c2mpatch to convert the fastfile's nav volume to Mac format was unsuccessful, further work is needed.
