Just merge it by setting a box to not respawn at start then hold a node in its place so when it spawns, it gets forced under so you can save and quit.
You can teletap by rapidly pressing A and then timing it right to grab it underground. You cant be Connection host to do this.
spawn a box where you want the teleporter merged at. plase spawn at start no than start a new round now spawn a tele right where the box is and wait for the box to spawn when it does save and quit. there you go the tele should now be under the level edit: crap someone already beat me to it
You can do it by sinking a wall and spawning a box where the node is, then grab it, save and quit. It should rest on the wall.
