As title say.
I was spawned in a car, outside of the lab (i was just in front of the lab though, so really close).
It was in a schoolbus, but i think the problem may come from the fact that it was an “enclosed” space within the car (because there is roof, closed door) & there is a lab under it.
Someone could check how it works, even if it may only rarely happen, if he have some time
