Autoload of mods is implemented in lastest patch on testlive and it is working.
I found 2 line in the client settings where you can enable auto download of mods.
I installed testlive on my server with a few mods and its working.
When you first click Join server you get a screen with a list of mods that it is checking, then the game exit again and start opp again with the mods.
It does this everytime you start the game unless you go to mods in the main menu and move the mods over to the middle column.
@Jens Erik, thank you.
