Strange error please help

[register]

I am adding many units to my mod and before I was modifying tech tree and somehow, somewhere, don't know when I did something wrong and I don't know how to track it back. Like in attachment, when I build first city or kill one unit am loosing the game what on earth is that?

That is unusual... what are the Victory conditions in Scenario Properties?

Default. I didn't touch Victory Conditions since the very beginning.

Do you have Regicide on?

 

[register]

Yes!!!!!! And no Kings attached to civilizations. Thank you

No problem . I've been using kings a fair amount so I've come across this when I had to redo something and forgot to replace the king units.
