Expected behavior

[llmlover]

Adding a 10s delay after spawning now returns something, but only two of the 12 passenger item_displays are visible, why is that?

This is odd, if it detects one passenger it should detect all, let me investigate as I face a similar issue

[SinanAkkoyun]

Fixed :) Please merge

[rom1504]

There is no correct PR on this topic

[SinanAkkoyun]

@rom1504 I'm curious, why incorrect? With originalVehicle.passengers = originalVehicle.passengers.splice(index, 1), you replace the passengers with only the removed entity. splice modifies the array, but it's return value is what it removed

However, could you please take a look at this? It would mean a lot to me
