Slight problem with investment in a city; please help?

[Alyngwen Clævyan]

So, I (for some reason) invested something in 2 cities (just to give it a try; I have no idea what the advantage of this is, but hell, it was just a small investment). However: I forgot which was the first city I invested in (and I understand I had to go back there for whichever reason). Is there somewhere I can see which places I invested in?
Thanks in advance, hope someone knows about this.

Investments allow you to access new item/goods and ships within a port its best to just invest in your home nation (ex London) unless it’s for specific trade items (ex India for spices) investments also allow you to gain court ranks which allow you to use different things within the nation
