More information.An update on Steam Workshop
Lord Captains!
We have important news regarding mods - unfortunately, we've rolled out the Steam Workshop support feature a bit too early, before all legal issues connected to it were fully settled. For now, we will have to take additional time and temporarily shut it down until everything is fully resolved on the legal side of things. We currently do not know how long it will take, but we will do our best to get this feature up and running again as soon as possible. Stay tuned for further updates.
We thank you a lot for understanding, and apologize for the inconvenience caused.
