How to disable need 4 gunpowder event...

Hi there,

Some questions:

How do you disable the 'gunpowder' and 'compass rose' events so that you don't require them beforehand to create like gunpowder weapons or advanced ships?

Is it possible to make a currently non-existent upgrade for an existing building (for instance, like there are 3 levels of sword smith - can I add a 4th?)

Thanks,

... BUMP...

Anyone who's been able to do this? Create gunpowder units without having to wait for the event or disabling the event? Ditto for the big ships?

Thanks,
Gilbert de Clare
