So after using your mod for a bit I decided I wanted to reroute my tracks. I used a deconstruction planer to have my bots do the dirty work. When I went to lay down my new route I had to relay some tracks that I should have left. When I hit a Point that I had used your mod to call my shuttle train I could no longer lay any tracks or anything for that matter in that location. The entity wasn't visible and was completely indestructible. I had to uninstall your mod to force the game to remove all aspects of these left behind ghost entities.
I get that you had to work some voodoo and create an "imaginary" train station to call a train to any location. I just wish the hidden item didn't hang around is all.
