Import Mod from Save

[ShooterMiku]

I am trying to import mod from save.
I play with vanila only which is base game, but they introduced Space age, Raised Rails and Qulity as mods, So I need to enable them in server for gameplay, but it seems if I uplaod my save it will meets json format problem,

I have exactly the same issue, hopefully will this be resolved

[MicMillon]

i have the same problem.. was able to upload my SpaceAge (DLC) game fine, but when i try to sync the mods, i get the following error:

Error unmarshalling requested struct JSON: unexpected end of JSON input

game was created using factorio build id 18705889

[skyzuma]

[gielles]

no, there is no new news :(

I was able to get this working.

On my desktop computer where I play Factorio, I zipped these directories:

1. C:\Program Files (x86)\Steam\steamapps\common\Factorio\data\elevated-rails
2. C:\Program Files (x86)\Steam\steamapps\common\Factorio\data\quality
3. C:\Program Files (x86)\Steam\steamapps\common\Factorio\data\space-age

I then placed those zip files in the directory that your docker container uses for mods. I run Unraid, so in my environment that is:

1. /mnt/user/appdata/factorio-server-manager/mods/

I then edited the mods-list.json file to look like this:

{
    "mods": [
        {
            "name": "base",
            "enabled": true
        },
        {
            "name": "elevated-rails",
            "enabled": true
        },
        {
            "name": "quality",
            "enabled": true
        },
        {
            "name": "space-age",
            "enabled": true
        },

            (the rest of your mods go here)

I also transferred one of my current savegames, which includes the 3 mods listed above, using the web GUI. Restarted the Docker container, and was able to login to the game with all mods, including Space Age, working.

this is working with all mods but this is not THE WAY to do this ... but i think the owner dont like it to "reapair" this function ...
