What is the event for turning estuaries into centres of trade?

[masteriw]

Does anyone know? I heard it was added in the last patch but didn't notice the estuary in Iraq turning into a CoT despite developing it a lot and placing my capital there as Oman.

Isn't the event about turning 'Natural Harbours' into Center of Trade?

 

[Vetgirig]

My natural Harbour of Manila went from +50% sailor to only +25% sailor because of this event

Estuaries remain estuaries. Natural ports can become coastal centers of trade

Oh, that's it then. Thanks!

@Trin Tragula Anyclue as to which file the event is located in/it's name?

I look at trade, random, province and a few others, and i forgot the most obvious one.... Colonial...

Where does this modifier come from though, is it an event?

That's just a thing that certain uncolonised provinces have from the start, such as Cape. Just like how London has the Important Centre of Trade modifer.

Yeah as mentioned above, its a fixed province modifier on game start. You can see all of them from the trade mapmode - they have a different icon to the estuaries.

 

[zedyue]

Thank you, I rarely colonize because I find it boring, and if I am colonizing - by that point of the game I'm not minmaxing provinces and looking at modifiers as much so I just assume trade/estuary
I didn't realize there was a third modifier at all

 

[Philadelphus]

The wiki has a full list; there aren't actually very many of them, only 14 in the game.

Sounds reasonable, since you'll only find them in uncolonised coastal provinces, and you only get at most 1 per trade node.
