Yeah I looked into it.. I had high hopes for that snap that you were talking about with the bunkers, but after I dug into the coding it appears that the code would limit the "snap" to a straight line, and doesnt allow for any angle changes. so basically, the only things that I could apply it to would be the straight track, that snaps together pretty well anyways from the grid snap.. maybe at some point somebody will be able to rewrite the code so that I can implement it the way I would like to, but that is above my skill level at the moment..
I am glad the move placeables mod helped! I will say, I know its tedious and time consuming, but it gets much easier with practice! I am pretty quick with it now
