[Help Request] Simulation freezes on episode 149

High Level Description

I am trying to use a customised scenario for an agent to learn how to park.

The scenario I'm using:

normal = TrafficActor(name="car", depart_speed=0)

traffic = {}
traffic["0"] = Traffic(
    trips=[
        Trip(
            vehicle_name=f"car_{i+1}",
            route=Route(
                begin=("gneE3", 1, (i+2) * 12),
                end=("gneE3", 1, "max")
            ),
            depart=0,
            actor=normal
        )
        for i in range(2)
    ],
    flows=[]
)

    
route = Route(begin=("gneE3", 1, 29), end=("gneE3", 1, 100))
ego_missions = [
    Mission(
        route=route,
        entry_tactic=TrapEntryTactic(
            start_time=0
        ),
    )
]

gen_scenario(
    scenario=Scenario(
        traffic=traffic,
        ego_missions=ego_missions,
    ),
    output_dir=Path(__file__).parent,
)

This is the xml:

Problems

When I use my scenario I get a freeze in episode 149 without any error. If I try a SMARTS scenario I don't have this problem.

Exit when killing:
