During hunts the ghost's movement patterns are pretty specific - they'll track line of sight and follow sound cues when pathing towards players. Their natural roaming from the favorite room happens regularly, but when hunting they get more aggressive with their pathing behavior. If you're seeing them near the truck, it's usually because they're following their targeting logic, trying to path through the building to reach players.

The ghost types really matter here too - mares will wander more frequently when there's light in their room, and wraiths have that nasty teleport ability that can make them appear in unexpected spots. The actual pathfinding during hunts checks accessible routes and player locations, which sometimes leads them into strange places especially if players are being evasive.

Tip: while they might look close to the truck sometimes, don't panic - the truck is completely safe and they can't actually enter it. Though rarely, some pathing bugs might make them appear to get closer than intended but that's just visual weirdness. The key is understanding they're following specific movement rules even when it looks random - tracking sound, checking line of sight, and using their type-specific abilities to hunt.
