After a lot of game and steam restarts I got it working now.
To get the mod to upload it deleted "mods_registry.json" and in the descriptor mod I added the name line.
So now for bardulon.mod
Code:
name="Bardulon v7.3"
path="mod/bardulon/"
and for descriptor.mod
Code:
name="Bardulon v7.3"
tags={
"Fixes"
"Gameplay"
"National Focuses"
}
supported_version="1.8.*"
remote_file_id="1706242702"
the first line in descriptor.mod wasn't there the first time, because of this sentence:
, which seemed that I don't need the name line in my descriptor.mod file.
The Mod then uploaded, but in the launcher it still said only supports version 1.7.3, and if I started the game with the mods active in the launcher, it didn't work ingame and the mod wasn't applied the checksum was still vanilla.
Now after a bit of waiting, again restarting of the game and deleting "mods_registry.json" it finally works.
