CtD with founding city.

[wibbol]

Hello, fellow modders.
Lately I picked up modding again, and started a small project which is a total conversion with three small eras. Total conversion, so I used this. After using TheLopez's Tech Tree Editor to add the first era few techs, I added a few basic units including a settler.
However.
When I test my mod I am given basic units including a settler. But when I found a city, the game crashes to desktop.
I also tried giving a scout the <bFound>1</bFound> but when the scout builds the city, the game crashes too...
What could cause this kind of crash?

If ethnic art is not the problem (just test if with different civs), then circular dependencies could be a problem.
I once had a crash because unit A upgraded to B, which upgraded to C, which then upgraded to A, and the game collapsed when you were able to build either unit, because it was stuck in an endless loop.
