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

[Arklancer]

Hello Everyone.
I'm having an issue again with the game crashing when I pull a lever to go to the next level.

This is the part in the hps file.
void OnStart()
{
SetEntityConnectionStateChangeCallback("Lever3", "Lever3");
}

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

void OnEnter()
{
}

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

This is the crash message, I have no idea what any of it even means inside the box. >.> - (See Attached)


I'm trying to finish the first chapter to TBH The Bro Heresy and I want to get it out this weekend at the latest.

Can somebody help me with this? >.<
