Using a lever to get to the next level (Crashing) Amnesia

[PutraenusAlivius]

void OnStart()
{
SetEntityConnectionStateChangeCallback("Lever3", "Lever3");
}

void Lever3(string &in asEntity, int alState)
{
if (alState == -1) //up
{
FadeOut(1);
SetPlayerActive(false);
ChangeMap("Excavation_02.map", "PlayerStartArea_1", "","");
}
}

void OnEnter()

{
}

void OnLeave()
{
SetupLoadScreen("LoadingText", "Ch01_Beginning", 5, "game_loading_rose.jpg");
}

Tell me if the problem still persists.
