Probably needs to be online...not sure on that note, but makes sense to be online.I have gotten Windows onto it now but my mods don't seem to be working, do I have to have the game finished? Does the game have to be online? Please help, I really don't know why it isn't working.
The game does not need to be finished, however, you may need to have a save that you have already escaped and have at least one Crib Teleportation "door" open. DLCs won't take effect until after this stage in the game, makes sense that Steamwork mods relying on content taken from after this point are activated the same way.
You can find out if the mods are even installed by navigating to "~\SteamLibrary\steamapps\workshop\content\206420", which will contain (number labelled, nine digit) folders for each Steamwork mod you have installed.
