So in my previous discussion i asked a question on how to install for linux runned computers. I figured it out later on and got asked to post on how i did it. So here it is.
And to answer the devoloper, haha no , no dual boot, but altought i have a second hard drive that i am planning to install windows on :).

So, as i've seen on my computer and some other people have said the same, steam usually saves the workshop files here
/home/name/.local/share/Steam/steamapps/workshop/content/48700/
Now just to say, maybe on your computer the map might not be named "48700". But once you're there, you will see maps with random numbers, for me "Age of Calradia Enchanted" map was named "590123705".

The amount of maps with random numbers depend on how many workshop mods you've downloaded. So how do you know whos who? Well you can click on the maps and view the "main.mbp" picture, (Reminder: The logo picture file can be named something else).

I found out by just clicking on the image and reading. Now once you know what mod, or maybe it was enchanted you we're looking for, you copy the map, and then go to /home/name/.local/share/Steam/Steam/steamapps/common/MountBlade Warband
Just go to the mount and blade warband map. Go into the "Modules" map, and paste it there, and rename it to whatever you want. I renamed mine to "enchanted".

Now go to your steam library. click on play mount and blade warband, and then check the other option for mod selecting, and change from native to the name you changed the map too. If you cannot find the steam map, go to your library, right click on the game, Mount and blade warband, and then click properties, then local files, and browse local files, and then you should be in the mount and blade map, from there you can go around the steam maps.
