Im unsure if you've had an update to change this, but in the preview screenshots, I see that a Cage Palisade is conencted with the Cage Gateway, so my assumption is that it is possible but I am unable to. It just keeps telling me there is no snap point.
I am playing Singleplayer, i have not put a foundation (because I did not think it needed it, being there wasn't one in the screenshot) and I have not tried to delete the mod yet (though I would like not to if I can help it as my download times are very, very slow)

Im hoping im just missing something, like its just not in this version, but the other version that has been mentioned, as I put a lot of material into making that gateway, but ya...thank you in advance ^^
