Well I digged a bit into it, this error never happened to me but I see how is happening thanks to the save game.

Seems Lumeris is passing through Arkab, an Academy-Owned System. The system wants to launch a hacking outcome, but fails to do so and locks the player.

The empire index for the function is indeed the Academy (index 14 in this game), but there's a collection of outcomes inside the function: this.pveOutcomesByEmpireIndex[operation.TargetSystem.EmpireIndex]; this object only has the major empires inside (player and the other 5 AIs), so, the pveOutcomesByEmpireIndex [14] is a non-set key, and the function fails to address this situation.

By that information, this can't be solved without editing the Assembly-Csharp DLL. Either disable the nakalim or penumbra to avoid this error.

For testing purposes, I added the blue code below before the error that leads to hang (red code), as it is a void function, that completely bypasses the error, and allows the game to continue. But probably that's a bandaid aid, and don't target the real problem.

if (!this.pveOutcomesByEmpireIndex.ContainsKey(operation.TargetSystem.EmpireIndex))
{
return;
}
List<StaticString> list = this.pveOutcomesByEmpireIndex[operation.TargetSystem.EmpireIndex];

Yes, you are right, I agree with you. But I also want to play that, and for that, I have to buy that and for now, I don't have any money for that. I thought to earn some extra easy money and the best intent way to make money is gambling, i thought to play and earn some money. but It is difficult to find a secure casino platform.
