Hey I'm new here i need help? And i made my own Country my quest is how can i add it to my game ?

I wanna export it but there stay they're nothing available to download how can i fix it? ^^

Are you still getting this issue, as I am able to download the mod "Tyralland"

Yeah i can download it but the prob is my country name is not showing how can i solved it? 

Just to check, you are following these steps after downloading from the site? (I'm assuming you have already created a new mod through the HOI4 launcher)

After you have downloaded your mod, open up the downloaded zip file. It should look something like this: (I am using WinRAR to open the file, so it may look a little different to what you see)

You will also need to navigate to the folder created by the HOI4 launcher for you mod, it should look something like this:

Now enter the numbered folder in the file exported from the site:

And copy the contents from here in to your mod's folder:

Once all of these are added, make sure to add the mod to your playset in the launcher: (the name shown will be whatever you called your mod, mine is "modding_export")

Then select the playset, and run the game.

Aight thank ya
