how does one do that?

the dev has to

You can fix the mod for now by going to the mod info file ({STEAM_LIBRARY}/steamapps/workshop/content/976730/2962107814/ModInfo.json) and changing MaxAppVersion.Minor from 3151 to 3272.

Your MaxAppVersion should now look like this:
"MaxAppVersion": {
"Major": 1,
"Minor": 3272,
"Patch": 0
},

Make sure all clients have this change if you're playing multiplayer. The mod works fine, inferno just needs to repackage his mod with an updated ModInfo file.

Thank you so much ! I have spent more than 1 hour rebooting the game, reinstalling etc.
That instantly fixed the mod :)

I am unable to open the ModInfo.json file. Is there some specific software needed to do this?
