It happens that I have created an extension of the Fjordur map and now I want to upload it as a mod, I have tried many ways and every time I upload the mod, it is uploaded without size 0.00B weight, so I don’t know what to do anymore

To upload a **mod extension** on a specific map, you must move **your modified level** to a folder inside the maps, specifically in **TheIslandSubMaps**.  
Only move the level that contains your changes.

As for the assets like structures and materials, they should remain in **your mod’s own folder** ,  
then upload it as a **Cook Game Mod**.
