Thank you for reporting! However this is not anew issue - this same situation also exist and existed for years within Ante Bellum. Every other aspect of vanilla colonial nations seems to be working the same - expect what you described. Sadly I have no idea whats the cause of it and how to solve it.

Bug report:

Whenever I proclaim a new colony, and try to colonize a province that is landlocked on the border of the colonial nation, it'll say

"This province can not be reached via any ports connected to our capital.
You can only colonize provinces that are adjacent to your own provinces (not colonies) or that are coastal provinces."

For example, if I colonize all Mexico + coastal provinces, I won't be able to do colonize any provinces that are in New Mexico or Arizona, if the only thing that borders these uncolonized provinces is THIS MODS colonial nation itself. If it's default colonial nation - no problem.

A small update: somewhat ironically the english were the only nation that got unique colonial nations with less than 12. I rectified this by adding 4 and bringing them up to 12. Additions include New Barsetshire and Palliser on the fantasy - in this case lets rather say literary - side.

Ok thank you.

12 - as all imported from Ante Bellum do. I plan on adding at least one more later - with the flag of my profile pic :)

How many CN's does Eastern Rome own?

My aim when making this mod has always been to make it possible to use unique colonial nation with the Random New World. It has been a coincidence that when i finally figured out how to do it it also worked for the Vanilla game and it also allowed you to choose the colonial nation for the region.
I intially made English and French colonial nations - for both of those it would not have made sense to integrate Ante Bellum. I also didnt have their permission at that point. If I never got it I would have simply made my own unique colonial nations - though than the scope of this would have been way more limited, most likely only covering the main colonizers.

Adding those designation would not make sense if you are using the Random New World. Also, if you cant discern the difference without me pointing it out, does it really matter? I think it would actually limit players freedom, by telling them what they are supposed to do. So sorry, but Im not goint to add this.

now the content has built up!
What was the goal if you weren't initially aiming to integrate these from Ante Bellum?
When I play Andalusia, I ask myself, what is Jazir-Al-Tenin? Which colonial region does it belongs to in Ante Bellum when picking the nation?

I would edit the language files in the event to be displayed like this, with Colonial Region shown after the name:
Jazir-Al-Tenin (Carribean)
for ease of establishing them precisely the same as in Ante Bellum itself.

New update - following my post below only Ante Bellum CN's this time.

I decided to change my approach. This far I have gone step by step on a country / nations basis. Now instead I will concentrate to include all Ante Bellum unique colonial nations I want included - this can be done pretty swiftly. And after that - while people can already have fun playing with those - I can take my time making adding fantasy, historical or non Ante Bellum alternate history colonial nations.

Thank you!

loved the mod so much, keep going, you´re doing great!

I just added dutch colonial nations - mostly historical boer republics. On the fantasy side Marienburg and Ketterdam.

I intend to - but its not a priority. Granada rarely survives, let alone formes Andalusia in the vanilla setting.

if you got a permission, do Andalusia from Ante Bellum
Think it wouldn't be too hard I guess, just copying the already done code

Just updated the mod with spanish colonial nations - 20 altogether. 12 from Ante Bellum that also allow for the formation of post colonial nations like Mexico, Peru, Cuba etc. The remaining 8 are Estalian kingdoms and Kasselia.

Klein-Venedig - havent heard of it before, but great idea. I will include it :). I also really like the Welser family crest which im going to use for its flag.

:) The plan has always been to step by step include the most important colonizers. Now that I have permission to use Ante Bellum colonial nations I will widen the scope a bit.

Put "Klein-veneding" 😭

@Dekken Your Welcome Dekken, but i have a suggestion, once your done with the Spanish Colonies, maybe consider adding in Portugal, German, Dutch, Scandinavian or even Italian Colonies which ever one comes first. Just remember to take your time with this submod and i hope it succeeds.

Thank you! I am currently working on a RNW tile but I plan to add spanish olonial nations latest this weekend.

i'm not gonna lie, i like the customized colonies that you can spawn in the mod, keep up the great work!
